    2003-05-23

    We found double-extreme black holes associated with the special geometry of the Calabi-Yau moduli space with the prepotential F = STU. The area formula is STU-moduli independent and has [SL(2, Z)]{sup 3} symmetry in space of charges. The dual version of this theory without prepotential treats the dilaton S asymmetric versus T,U-moduli. We display the dual relation between new (STU) black holes and stringy (S|TU) black holes using particular Sp(8,Z) transformation. The area formula of one theory equals the area formula of the dual theory when expressed in terms of dual charges. We analyze the relation between (STU) black holes to string triality of black holes: (S|TU), (T|US), (U|ST) solutions. In democratic STU-symmetric version we find that all three S and T and U duality symmetries are non-perturbative and mix electric and magnetic charges.

    Full Text Available Dent disease is an x-linked disorder of proximal renal tubular dysfunction that occurs almost exclusively in males. It is characterized by significant, mostly low molecular weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis, and chronic kidney disease. Signs and symptoms of this condition appear in early childhood and worsen over time. There are two forms of Dent disease, which are distinguished by their genetic cause and pattern of signs and symptoms (type 1 and type 2. Dent disease 2 is characterized by the features described above and also associated with extrarenal abnormalities (they include mild intellectual disability, hypotonia, and cataract. Some researchers consider Dent disease 2 to be a mild variant of a similar disorder called Lowe syndrome.We represent a case of a 3-year old boy with significant proteinuria in the nephrotic range and hypercalciuria. We confirmed Dent disease type 1 by genetic analysis.

    The equations of null geodesics in the STU family of rotating black hole solutions of supergravity theory, which may be considered as deformations of the vacuum Kerr metric, are completely integrable. We propose that they be used as a foil to test, for example, with what precision the gravitational field external to the black hole at the centre of our galaxy is given by the Kerr metric. By contrast with some metrics proposed in the literature, the STU metrics satisfy by construction the dominant and strong energy conditions. Our considerations may be extended to include the effects of a cosmological term. We show that these metrics permit a straightforward calculation of the properties of black hole shadows.

    Aspergillus nidulans StuA and Neurospora crassa ASM-1 are orthologous APSES (ASM-1, PHD1, SOK2, Efg1, StuA) transcription factors conserved across a diverse group of fungi. StuA and ASM-1 have roles in asexual (conidiation) and sexual (ascospore formation) development in both organisms. To address the hypothesis that the last common ancestor of these diverse fungi regulated conidiation with similar genes, asm-1 was introduced into the stuA1 mutant of A. nidulans. Expression of asm-1 complemented defective conidiophore morphology and restored conidia production to wild type levels in stuA1. Expression of asm-1 in the stuA1 strain did not rescue the defect in sexual development. When the conidiation regulator AbaA was tagged at its C-terminus with GFP in A. nidulans, it localized to nuclei in phialides. When expressed in the stuA1 mutant, AbaA::GFP localized to nuclei in conidiophores but no longer was confined to phialides, suggesting that expression of AbaA in specific cell types of the conidiophore was conditioned by StuA. Our data suggest that the function in conidiation of StuA and ASM-1 is conserved and support the view that, despite the great morphological and ontogenic diversity of their condiphores, the last common ancestor of A. nidulans and N. crassa produced an ortholog of StuA that was involved in conidiophore development. © 2015 by The Mycological Society of America.

    Full Text Available Abstract Dent's disease is a renal tubular disorder characterized by manifestations of proximal tubule dysfunction, including low-molecular-weight proteinuria, hypercalciuria, nephrolithiasis, nephrocalcinosis, and progressive renal failure. These features are generally found in males only, and may be present in early childhood, whereas female carriers may show a milder phenotype. Prevalence is unknown; the disorder has been reported in around 250 families to date. Complications such as rickets or osteomalacia may occur. The disease is caused by mutations in either the CLCN5 (Dent disease 1 or OCRL1 (Dent disease 2 genes that are located on chromosome Xp11.22 and Xq25, respectively. CLCN5 encodes the electrogenic Cl-/H+ exchanger ClC-5, which belongs to the CLC family of Cl- channels/transporters. OCRL1 encodes a phosphatidylinositol bisphosphate (PIP2 5-phosphatase and mutations are also associated with Lowe Syndrome. The phenotype of Dent's disease is explained by the predominant expression of ClC-5 in the proximal tubule segments of the kidney. No genotype-phenotype correlation has been described thus far, and there is considerable intra-familial variability in disease severity. A few patients with Dent's disease do not harbour mutations in CLCN5 and OCRL1, pointing to the involvement of other genes. Diagnosis is based on the presence of all three of the following criteria: low-molecular-weight proteinuria, hypercalciuria and at least one of the following: nephrocalcinosis, kidney stones, hematuria, hypophosphatemia or renal insufficiency. Molecular genetic testing confirms the diagnosis. The differential diagnosis includes other causes of generalized dysfunction of the proximal tubules (renal Fanconi syndrome, hereditary, acquired, or caused by exogenous substances. Antenatal diagnosis and pre-implantation genetic testing is not advised. The care of patients with Dent's disease is supportive, focusing on the treatment of hypercalciuria and

    This paper evaluates the criticality of dents in a framework more general than acceptable dent depth. Analysis is done with reference to typical line pipe mechanical properties, as well as true-fracture ductility and fracture-initiation toughness, to evaluate severity and rank criticality. Results here and a sister paper are presented that show current code-acceptance criteria for dents are over conservative in general, sometimes significantly, in particular for plain dents. Full-scale test data are introduced to support the analytical results. Results are also presented to assist in evaluating the utility and accuracy of in-line inspection deformation tools, and their calibration with reference to measured field dent size. (author)

  13. Lateral Root Development in Potato Is Mediated by Stu-mi164 Regulation of NAC Transcription Factor

    Directory of Open Access Journals (Sweden)

    Li Zhang

    2018-03-01

    Full Text Available The NAC designation is derived from petunia (Petunia hybrida gene NO APICAL MERISTEM (NAM and Arabidopsis genes ATAF1/ATAF2 and CUP-SHAPED COTYLEDON2 (CUC2, which belongs to the family of plant-specific transcription factors (TFs, and plays important role in plant development processes, such as response to biotic and abiotic stress, and hormone signaling. MicroRNAs (miRNAs are a class of small, non-coding endogenous RNAs which play versatile and significant role in plant stress response and development via negatively affecting gene expression at a post-transcriptional level. Here, we showed that Stu-mi164 had a complementary sequence in the CDS sequence of potato NAC TFs, and that NAC expression exhibited significant differences under osmotic stress. We measured expression levels of the Stu-mi164 target gene StNAC262 between control and PEG-treated plants using real-time PCR, and the results demonstrated that they had inverse relationship. We suggested that Stu-miR164 might drive overexpression of NAC gene under osmotic stress in potato. To confirm the regulation of NAC TFs by Stu-mi164, we developed transgenic plants, using Agrobacterium tumefaciens–mediated transformation, of the potato cultivars “Gannongshu 2” and “Kexin 3” overexpressing the Stu-mi164 or the TF StNAC262. Real-time PCR analysis of transgenic potato plants under osmotic (PEG stress, showed that potato plants overexpressing Stu-mi164 had reduced expression of StNAC262 and their osmotic resistance decreased. Furthermore, these plants had low number of lateral roots although the same length as the control. Our findings support the regulatory role of Stu-miRNAs in controlling plant response to osmotic stress via StNAC262.

    The Scent Transfer UnitTM (STU-100) is a portable vacuum that uses airflow through a sterile gauze pad to capture a volatiles profile over evidentiary items for subsequent canine presentation to assist law enforcement personnel. This device was evaluated to determine its ability to trap and release organic compounds at ambient temperature under controlled laboratory conditions. Gas chromatography-mass spectrometry (GC-MS) analyses using a five-component volatiles mixture in methanol injected directly into a capture pad indicated that compound release could be detected initially and three days after time of collection. Additionally, fifteen compounds of a 39-component toxic organics gaseous mixture (10-1,000 ppbv) were trapped, released, and detected in the headspace of a volatiles capture pad after being exposed to this mixture using the STU-100 with analysis via GC-MS. Component release efficiencies at ambient temperature varied with the analyte; however, typical values of approximately 10 percent were obtained. Desorption at elevated temperatures of reported human odor/scent chemicals and colognes trapped by the STU-100 pads was measured and indicated that the STU-100 has a significant trapping efficiency at ambient temperature. Multivariate statistical analysis of subsequent mass spectral patterns was also performed.

    Full Text Available INTRODUÇÃO: O cisto dentígero é o segundo cisto odontogênico mais frequente nos maxilares. É uma lesão benigna, derivada do epitélio odontogênico da coroa de um dente não erupcionado, porém de etiopatogenia incerta. São geralmente radiotransparentes e, mais comumente, uniloculares. Estas lesões são observadas em exames de rotina ou quando não ocorre o irrompimento de um dente permanente. Os terceiros molares inferiores e os caninos superiores são os dentes mais acometidos, sendo também alta a ocorrência desta lesão em dentes supranumerários e associados a odontomas. O cisto dentígero ocorre principalmente nas três primeiras décadas de vida, tendo um crescimento lento e assintomático; pode atingir dimensões consideráveis, causando deformidade facial, impactação e deslocamento de dentes e/ou estruturas adjacentes. OBJETIVO: Definição das técnicas de marsupialização e enucleação, bem como consideração de critérios objetivos importantes para o plano de tratamento, como tamanho do cisto, idade, proximidade com estruturas anatômicas e importância clínica do dente envolvido. Apesar das peculiaridades clínicas de cada caso e do método de tratamento escolhido, o prognóstico destas lesões é favorável, quando se emprega apropriada terapêutica. MATERIAL E MÉTODO: O presente estudo apresentará um relato de caso tratado através da manobra de descompressão seguida de enucleação, bem como uma discussão acerca das modalidades de tratamento. RESULTADO: O paciente encontra-se em pós-operatório de dois anos sem sinais de recidiva da lesão e ausência de parestesias em face. CONCLUSÃO: A técnica empregada preservou a função neurossensorial e mostrou-se eficiente para a cura da lesão.

  17. Modeling and Calculation of Dent Based on Pipeline Bending Strain

    Full Text Available The bending strain of long-distance oil and gas pipelines can be calculated by the in-line inspection tool which used inertial measurement unit (IMU. The bending strain is used to evaluate the strain and displacement of the pipeline. During the bending strain inspection, the dent existing in the pipeline can affect the bending strain data as well. This paper presents a novel method to model and calculate the pipeline dent based on the bending strain. The technique takes inertial mapping data from in-line inspection and calculates depth of dent in the pipeline using Bayesian statistical theory and neural network. To verify accuracy of the proposed method, an in-line inspection tool is used to inspect pipeline to gather data. The calculation of dent shows the method is accurate for the dent, and the mean relative error is 2.44%. The new method provides not only strain of the pipeline dent but also the depth of dent. It is more benefit for integrity management of pipeline for the safety of the pipeline.

    The temporal and spatial regulation of β-1,3-glucan synthesis plays an important role in morphogenesis during fungal growth and development. Northern blot analysis showed that the transcription of fksA, the gene encoding β-1,3-glucan synthase in Aspergillus nidulans, was cell-cycle-dependent and increased steadily over the duration of the vegetative period, but its overall expression during the asexual and sexual stages was fairly constant up until the time of transcription cessation. In an A. nidulans strain mutated in the eukaryotic bHLH-like APSES transcription factor stuA1, the transcriptional level of fksA, and consequently the content of alkali-insoluble cell wall β-glucan, significantly increased at the conidial chain formation and maturation stage. Electrophoretic mobility shift assays revealed that StuA was bound to StREs (StuA Response Elements) on the fksA promoter region. Promoter analysis with sGFP-fusion constructs also indicated the negative regulation of fksA expression by StuA, especially during asexual development. Taken together, these data suggest that StuA plays an important role in cell wall biogenesis during the development of A. nidulans, by controlling the transcription level of fksA.

  1. Experimental evaluation of residual stresses produced by plain dents in pipelines

    A dent means a permanent plastic deformation of the circular cross-section of the pipe. Dents are potentially danger for structural integrity of onshore and offshore pipelines, because it causes a local stress and strain concentration. It is also expected that residual stresses are introduced by the non-uniform plastic deformation. A plain dent is a dent which causes a smooth change in the curvature of the pipe wall that contains no wall thickness reductions (such as a gouge or a crack) or other defects or imperfections (such as a weld). This work presents an experimental evaluation of residual stresses intensification due to plain dents introduced through the same indentation process, in samples made of the same steel line pipe, commonly used in the pipeline industry. The residual stresses were measured in the longitudinal and circumferential directions in preselected points by X-ray diffraction technique, before indentation. After the samples have been dented, the residual stresses were measured once more at the same points, for comparison. All samples presented a similar behavior of the residual stresses due to induced plain dents, and the X-ray diffraction technique shows itself as an efficient methodology of stress measurement in pipelines.

    It is highly likely that the accumulation of sludge (deposits) on the tube sheet is clearly associated with the denting occurrence. More specifically, it is commonly believed that an aggressive crevice environment formed within the deposits or in the shallow tight tube sheet to tube crevice below the deposits is at the origin of the denting (tube deformation), and, when present, the consequent stress corrosion cracking (SCC). There are described a set of strategies that have been followed since the emergence of the TTS denting phenomenon on Steam Generator of the Nuclear Power Plants Asco I and II, influenced by the presence of hard sludge in the tube plate of Steam Generators, their results and the evolution of the phenomenon in relation to the various measures taken.

    Full Text Available Purpose: To report a case of temporary bilateral corneal denting in a patient who underwent cardiovascular surgery under general anesthesia. Observations: A 71-year-old male with no history of ophthalmological disease experienced bilateral corneal denting immediately after undergoing surgery for aneurysm of the thoracic aorta under general anesthesia. Anesthesia was induced with propofol and maintained with rocuronium bromide and remifentanil hydrochloride. The initial examination revealed significant denting on the surface of both the corneas and ocular hypotension. Visual evaluation could not be performed due to the patient's low level of consciousness resulting from delayed emergence from anesthesia. After applying tropicamide and phenylephrine ophthalmic solution for fundus examination, the ocular morphology improved. Ocular pressure was normal on the day after surgery, and creasing on the surface of the corneas had disappeared. Conclusions: and Importance: We experienced a patient with bilateral corneal denting following a cardiovascular surgery under general anesthesia. The dents could be attributed to augmentation of ocular hypotension using several types of anesthesia at relatively high doses.

    Androgens have an anti-proliferative effect on endometrial cells. Human androgen receptor (AR) gene contains two polymorphic short tandem repeats of GGC and CAG, and a single-nucleotide polymorphism on exon 1 that is recognized by the restriction enzyme, StuI. Prior studies have shown that the lengths of the CAG repeat are inversely and linearly related to AR activity and associated with endometrial cancer. However, little is known about the GGC repeat and the StuI polymorphism of the AR gene. Thus, we investigated whether these AR polymorphisms are risk factors for endometrial cancer. To test this hypothesis, the genetic distributions of these polymorphisms were investigated in blood samples from endometrial cancer patients and healthy controls. The allelic and genotyping profiles were analyzed by polymerase chain reaction (PCR), PCR-restriction fragment length polymorphism (PCR-RFLP), and direct DNA sequencing, and analyzed statistically. The GGC repeat was significantly longer in endometrial cancer patients as compared to normal healthy controls. In general, an increased risk of endometrial cancer was found with increasing GGC repeat. The relative risk for the 17 GGC repeat was greater than 4, as compared to controls. However, the StuI polymorphism was not significantly different between patients and controls. The findings suggest that increased numbers of GGC repeat on the AR gene may be a risk factor for endometrial cancer

  7. Evaluation of the eddy-current method for the inspection of steam generator tubing: denting

    Brown, S.D.; Flora, J.H.

    1977-01-01

    Continued evaluation of existing eddy-current in-service inspection (ISI) methods for steam generator tubing has emphasized the effects of denting. Denting is a circumferential deformation of the tube in the support region as a result of the formation of a magnetite, Fe 3 O 4 , corrosion product on the carbon steel tube support plate in the crevice between the support plate and the tube wall. The effects of denting on eddy current inspection are twofold: (1) The detection and measurement of defects in the dented region is hampered by the distortion of the eddy-current response signals caused by the dents and (2) large dents may prevent the passage of high fill factor probes forcing the inspection teams to use a smaller probe in undented regions. Unless appropriate measures are taken, less reliable detection of defects and estimation of their depth can result. The report presents an experimental evaluation of existing eddy-current ISI methods when used to inspect dented regions. Tubes were mechanically dented to simulate various degrees of service induced denting. These tubes were then inserted in carbon steel tube support plates and the crevice region between the support plate and tube was subsequently packed with powdered magnetite. Diametral dent sizes considered during this program varied between 1 and 10 mils. Eddy-current signal patterns and strip chart recordings were obtained using a variety of test parameters, such as frequency, phase rotation and coil configuration, on tube samples containing various degrees of denting and with several types of defects in the dented system

    We study the extended thermodynamics, obtained by considering the cosmological constant as a thermodynamic variable, of STU black holes in 4-dimensions in the fixed charge ensemble. The associated phase structure is conjectured to be dual to an RG-flow on the space of field theories. We find that for some charge configurations the phase structure resembles that of a Van der Waals gas: the system exhibits a family of first order phase transitions ending in a second order phase transition at a critical temperature. We calculate the holographic entanglement entropy for several charge configurations and show that for the cases where the gravity background exhibits Van der Waals behavior, the entanglement entropy presents a transition at the same critical temperature. To further characterize the phase transition we calculate appropriate critical exponents and show that they coincide. Thus, the entanglement entropy successfully captures the information of the extended phase structure. Finally, we discuss the physical interpretation of the extended space in terms of the boundary QFT and construct various holographic heat engines dual to STU black holes.

  12. Denting of Inconel steam generator tubes in pressurized water reactors. Third informal report

    International Nuclear Information System (INIS)

    van Rooyen, D.; Weeks, J.R.

    1977-08-01

    The recent plant operating experience and laboratory test results on the phenomenon of denting in recirculating PWR steam generators is reviewed. Although denting was first reported only in plants that were converted from phosphate to AVT, it has now also been observed in plants still on phosphate, as well as in some that started on AVT. In some units, slightly abnormal eddy current signals have been observed at the top of the tube sheets. The degree of denting in operating steam generators may be related to the levels and duration of chloride inleakage. Chloride, however, is not the only active ingredient, and does not seem to give denting until local acid conditions arise; consequently, it may be necessary for soluble copper and/or nickel ions to be present to promote the denting reaction. Chloride concentrations in actively corroding crevices can increase by several orders of magnitude over the bulk coolant. It is thus difficult to develop a basis for Cl - specifications for secondary water. Maintaining Cl - low enough to prevent denting may be unmanageable without full flow condensate demineralization in coastal plants with copper alloy condensors and feedwater lines. Cathodic depolarization by oxidizing species are thought to promote the formation of acid chlorides in crevices and trigger the denting reactions; some ions may also catalyze the rapid formation of magnetite. These, and other mechanistic aspects of denting are discussed. The implications of the Inconel 600 tube defects at Ginna in non-dented areas, originating from the primary side, are also discussed

  16. Analysis Of Dynamic Dent Resistance Of Auto Body Panel

    International Nuclear Information System (INIS)

    Deolgaonkar, S. S.; Nandedkar, V. M.

    2007-01-01

    In automotive industry there is increasing demand for higher quality exterior panels, better functional properties and lower weight. The demand for weight reduction has led to thinner sheets, greater use of high strength steels and a change from steel to aluminum grades. This thickness reduction, which causes decrease in the dent resistance, promoted examination of the dent resistance against static and dynamic concentrated loads. This paper describes an investigation of the suitability of explicit dynamic FE analysis as a mean to determine the dynamic dent properties of the panel. This investigation is carried out on the body panel of utility vehicle and covers two parts, in first experimental analysis is carried out on developed test rig, which is interfaced with the computer. This test rig measures deflection with accuracy of .001mm. The experimental results are then compared with the simulation results, which is the second part. Simulation is carried with non-linear transient dynamic explicit analysis using Ansys -Ls Dyna. The experimental results show great accuracy with simulation results. The effect of change in thickness and geometry of the existing fender is then studied with help of simulation technique. By considering the best possible option overall weight of fender is reduced by 7.07 % by keeping the dent resistance of the panel constant

    Stable de Sitter solutions in minimal F-term supergravity are known to lie close to Minkowski critical points. We consider a class of STU-models arising from type IIB compactifications with generalised fluxes. There, we apply an analytical method for solving the equations of motion for the moduli fields based on the idea of treating derivatives of the superpotential of different orders up to third as independent objects. In particular, supersymmetric and no-scale Minkowski solutions are singled out by physical reasons. Focusing on the study of dS vacua close to supersymmetric Minkowski points, we are able to elaborate a complete analytical treatment of the mass matrix based on the sGoldstino bound. This leads to a class of interesting universal dS vacua. We finally explore a similar possibility around no-scale Minkowski points and discuss some examples.

  19. Denting of Inconel 600 steam generator tubes in pressurized water reactors

    International Nuclear Information System (INIS)

    Van Rooyen, D.; Weeks, J.R.

    1976-10-01

    Rapid, localized corrosion of carbon steel tube support plates (TSP) has led to cases of denting of steam generator tubes, due to the pressure of corrosion products formed in crevices between the tubes and TSP holes. The corrosion product is mainly magnetite (Fe 3 O 4 ), formed in ''run-away'' fashion as a result of local chemistry changes when an extended operation with phosphate (PO 4 ) treatment of the secondary coolant is followed by an all volatile treatment (AVT). The rate of the ''run-away'' magnetite formation, and therefore, the extent of damage will probably vary with the amounts of the harmful chemicals present and with temperature. Leaky condensers are felt to be responsible for the presence of Cl - ions, and for the observation that denting is more extensive in plants with salt water cooled condensers. It is possible that thermal cycles assist the denting process, both by mechanical and chemical ratchetting mechanisms. Recommendations are presented concerning the continued operation of plants with observed denting

    2017-11-15

    In this paper, we consider a deformed STU model in four dimensions including both electric and magnetic charges. Using the AdS/CFT correspondence, we study holographic superconductors and obtain transport properties like electrical and thermal conductivities. We obtain transport properties in terms of the magnetic charge of the black hole and interpret it as the magnetic monopole of dual field theory. We find that the presence of the magnetic charge is necessary to have maximum conductivities, and the existence of a magnetic monopole with a critical charge (137 e) to reach the maximum superconductivity is important. Also, we show that the thermal conductivity increases with increasing of the magnetic charge. It may be concluded that the origin of superconductivity is the magnetic monopole. (orig.)

    This paper describes a method under development at PETROBRAS R and D Center (CENPES) to estimate the fatigue life of plain dents. This method uses the API Publication 1156 as a base to estimate the fatigue life of dome shaped plain dents and the Pipeline Defect Assessment Manual (PDAM) approach to take into account the uncertainty inherent in the fatigue phenomenon. CENPES method, an empirical and a semi-empirical method available in the literature were employed to estimate the fatigue lives of 10 plain dents specimens of Year 1 of an ongoing test program carried out by BMT Fleet Technology Limited, with the support of the Pipeline Research Council International (PRCI). The results obtained with the different methods are presented and compared. Furthermore some details are given on the numerical methodology proposed by PETROBRAS that have been used to describe the behavior of plain dents. (author)

    Full Text Available INTRODUÇÃO: A pulpotomia em dentes decíduos é uma técnica conservadora de terapia pulpar amplamente utilizada em Odontopediatria, sendo de fundamental importância para evitar a perda prematura desses dentes, quer seja por alterações provocadas pela cárie dentária ou traumatismo dentário. Apesar de ser uma técnica estudada há muitos anos, causa muitas controvérsias e discussões, principalmente em termos de biocompatibilidade dos medicamentos empregados e pelas dificuldades e falhas no diagnóstico da condição pulpar. OBJETIVO: Por meio de uma revisão sistemática da literatura, no período compreendido entre 2000 e 2011, e com enfoque em estudos clínicos randomizados, revisões sistemáticas e meta-análises, este trabalho teve como objetivo discutir, com base em evidências científicas, alternativas para o tratamento de pulpotomia em dentes decíduos humanos. CONCLUSÃO: As evidências científicas fidedignas com o uso de materiais capeadores pulpares e as técnicas de Eletrocirurgia e Laser de Baixa Potência foram escassas. Desta forma, sugere-se a realização de estudos complementares bem delineados estatisticamente para maiores esclarecimentos. As informações geradas em tais experimentos poderão contribuir para um melhor entendimento dos mecanismos da terapia pulpar, podendo gerar o desenvolvimento de protocolos com novas formas terapêuticas, que visam a melhorar a terapia pulpar em dentes decíduos.

    Pancreatic resections are among the most complex procedures in visceral surgery. While mortality has decreased substantially over the past decades, morbidity remains high. The volume-outcome correlation in pancreatic surgery is among the strongest in the field of surgery. The German Society for General and Visceral Surgery (DGAV) established a national registry for quality control, risk assessment and outcomes research in pancreatic surgery in Germany (DGAV SuDoQ|Pancreas). Here, we present the aims and scope of the DGAV StuDoQ|Pancreas Registry. A systematic assessment of registry quality is performed based on the recommendations of the German network for outcomes research (DNVF). The registry quality was assessed by consensus criteria of the DNVF in regard to the domains Systematics and Appropriateness, Standardization, Validity of the sampling procedure, Validity of data collection, Validity of statistical analysis and reports, and General demands for registry quality. In summary, DGAV StuDoQ|Pancreas meets most of the criteria of a high-quality clinical registry. The DGAV StuDoQ|Pancreas provides a valuable platform for quality assessment, outcomes research as well as randomized registry trials in pancreatic surgery.

    2008-01-01

    Experimental measurements are always affected by some noise and errors caused by inherent inaccuracies and deficiencies of the experimental techniques and measuring devices used. In some fields, such as strain calculations in a dented pipe, the results are very sensitive to the errors. This paper presents a filtering algorithm to remove noise and errors from experimental measurements of radial displacements of a dented pipe. The proposed filter eliminates the errors without harming the measured data. The filtered data can then be used to estimate membrane and bending strains. The method is very effective and easy to use and provides a helpful practical measure for inspection purposes

    The response of the tube supports is one of the important considerations of tube denting in a steam generator. Investigations have indicated that damaged tube supports have the potential to distort and damage tubes. This investigation considers the response to tube denting of the Combustion Engineering type tube supports. Drilled support plates and eggcrate tube supports are tested in a model steam generator in which tube denting is induced. The experimental data is used to verify and refine analytical predictor models developed using finite element techniques. It was found that analytical models underpredicted the deformations of the tube supports and appropriate modifications to enhance the predictive capability are identified. Non-destructive examination methods are evaluated for application to operating steam generators. It was found that the standard eddy current and profilometry techniques are acceptable methods for determining tube deformations, but these techniques are not adequate to assess tube support damage. Radiography is judged to be the best available means of determining the extent and progression of damage in tube supports

    Dent disease is an X-linked tubulopathy mainly caused by inactivating mutations of CLCN5. Features of Bartter syndrome such as hypokalemic metabolic alkalosis are rarely observed in patients with Dent disease. We report a Japanese male patient with Dent disease who also manifested features of Bartter syndrome. At the age of 3 years, he was diagnosed with Dent disease based on low molecular weight proteinuria and hypercalciuria. One year later, he was found to have features of Bartter syndrome, i.e., hypokalemia and metabolic alkalosis, and high levels of plasma renin activity and aldosterone with a normal blood pressure. Despite medical interventions, he developed chronic kidney disease stage 3 at the age of 21 years. To investigate the molecular basis of his disease, CLCN5, KCNJ1, SLC12A1, and CLCkb were analyzed and a novel mutation (Y567X) in CLCN5 was identified. Hypokalemic metabolic alkalosis is a rare manifestation in Dent disease. It is speculated that Dent patients with features of Bartter syndrome are susceptible to progression to renal failure. To study this hypothesis, additional observations and long-term follow-up of such patients are necessary.

    It is well known that the breastplates of many armours from the later 16th century and the 17th century bear the hemispherical dents generally known as proof marks. It has been taken as axiomatic that these marks were made in order to demonstrate the armours’ effectiveness against firearms. If however some of these dents are compared with dents which are the result of battle damage, it appears that they were made by energy levels of a different order of magnitude, and offer little guarantee as to the “proof” of the armour.



    Como es bien sabido, muchos petos de armaduras de finales del siglo XVI y del XVII tienen abolladuras semiesféricas conocidas como pruebas de arcabuz. Se ha considerado axiomático que estas abolladuras fueron hechas para demostrar la efectividad de las armaduras frente a las armas de fuego. Sin embargo, si se comparan con otras debidas a daños en combate, parece que fueron producidas por energías de diferente orden o magnitud, al tiempo que ofrecen pocas garantías como “pruebas” de las armaduras.

    Dent's syndrome is a rare inherited tubulopathy. Factors influencing renal function in this disease are not well known. The aim of our study is to investigate the evolution of the Dent's syndrome in renal plan. The study was retrospective and conducted in 2006, concerning four brothers. The genetic defect was a mutation S244L missense in exon 6 of gene CLCN5. Various parameters were studied. Patients were 8.5 to 21-years-old at the beginning of the follow-up. Two of them had chronic renal insufficiency (CRI) which evolved, at least 7 years of moderate to terminal stage. Tubular signs were made of hypokalemia, hypercalciuria, hypophosphatemia and proteinuria mostly β2 microglobulin. Improvement of these abnormalities was obtained with symptomatic treatment which has not always been well tolerated. A case of beginner nephrocalcinosis was observed. There was size and weight delay at the beginning of patient monitoring. Dent's syndrome may be complicated by CRI. It seems to appear in the second decade of life and hypercalciuria would contribute to it. Our CRI patients had significant bone disease. The hypercalciuria and proteinuria are factors over which we try to act. Clinical trials are needed to evaluate the efficacy of treatment on the reduction of CRI or its progression by reducing these factors in patients with Dent's syndrome.

    2007-01-01

    Diamond like Carbon (DLC) film is a hard amorphous carbon hydride film formed by Physical or Chemical vapor deposition (PVD or CVD) techniques. Due to its unique properties especially high hardness, lower coefficient of friction and lubricious nature, these coatings are not only used to extend the life of cutting tools but also for non cutting applications such as for forming dies, molds and on many functional parts of textile. In the present work two techniques were employed i.e. PVD and CVD for deposition of diamond like carbon film on textile dents. These dents are used as thread guider in high speed weaving machine. The measurement of coating thickness, adhesion, hardness and roughness values indicates that overall properties of DLC coating developed by PVD LARC technology reduces abrasion and increases the workability and durability of textile dents as well as suppress the need of lubricants.

    Full Text Available Com objetivo de avaliar a incidência de placa bacteriana dentária, foram utilizados 30 cães, sem raça definida, distribuídos em três grupos iguais, de acordo com a faixa etária, sendo o grupo I de 0 a 2 anos, o grupo II de 3 a 5 anos e o grupo III acima de 6 anos. Os animais foram submetidos a anestesia geral e sobre os dentes foi aplicado cloreto de metilrosanilina, para evidenciar acúmulos bacterianos. As placas encontravam-se distribuídas em 80,99% no grupo I, 71,45% no grupo II e 83,96% no grupo III. Os grupos dentários foram considerados separadamente, apresentando índices de 64,84% nos dentes incisivos, 84,80% nos caninos, 87,23% nos pré-molares e 78,34% nos molares. Nos três grupos de cães observou-se índices semelhantes de placa bacteriana nos diferentes grupos dentários. Os animais do grupo II e o grupo de dentes incisivos apresentaram menores índices de placa bacteriana.To avaliate the incidence of bacterial plaque 30 mogreal dogs were utilizated, distributed among three equal groups. According to age, group I was composed of 0 to 2 years-old dogs, group II was 3 to 5 years-old, and group III over 6 years-old. The animals underwent a general anesthesia and metilrosanilin cloret was applied over the tooth, to evidence the bacterial mass. The plaques were distributed to 80.99% in group I, 71.42% in group II and 83.96% in group III. The dental groups were considerated apart, showing index of 64.84% on the incisar tooth, 84.80% on the canine tooth, 87.23% on the premolar tooth, and 78.34% on the molar tooth. At the dogs groups, similar Índex of bacterial plaque were observed on the diffèrent dental groups. The dogs from group II and the incisive tooth group showed minar bacterial plaque index.

    Full Text Available O objetivo deste trabalho foi analisar as percepções de um grupo de idosos sobre a perda de dentes. Realizou-se uma pesquisa qualitativa que utilizou O Discurso do Sujeito Coletivo como técnica metodológica para a ordenação dos dados. A análise das entrevistas e a construção do Discurso do Sujeito Coletivo revelaram informações sobre os pensamentos e valores associados à perda de dentes no grupo. Os principais resultados sugerem que a falta de dentes trouxe problemas funcionais e psicológicos, mas que parecem ser compensados pela resolução do problema estético. As justificativas reveladas pelo sujeito coletivo para o edentulismo refletem predominantemente o modelo de atenção à saúde, em que predominam procedimentos cirúrgico-restauradores e reabilitadores, em detrimento de ações preventivas e educativas. Desta forma, torna-se imprescindível o desenvolvimento de iniciativas no campo da educação e prevenção em saúde bucal, enfatizando ações voltadas para a atenção integral do idoso, destacando-se a dimensão social das doenças e o papel do Estado como provedor da saúde e da qualidade de vida de todos os cidadãos.

    In the Payload Changeout Room, Launch Pad 39B, United Space Alliance and NASA workers look at the replacement main propulsion system liquid hydrogen recirculation line (left) to be installed in Shuttle Discovery's aft compartment. At right is the dented line that has been removed. The 12-inch-long dent was discovered during routine aft compartment inspections Tuesday, Dec. 7. The line recirculates hydrogen from the Shuttle main engines back to the external tank during prelaunch engine conditioning. The line is being replaced and managers expect the replacement work to take about 3 days, followed by system retests and final aft compartment close-outs. Preliminary assessments reflect a launch date of Space Shuttle Discovery on mission STS-103 no earlier than Dec. 16. STS-103 is the third servicing mission for the Hubble Space Telescope.

    1997-01-01

    Full Text Available Os autores testaram a resistência ao cisalhamento de dentes submetidos a duas técnicas de clareamento. Foram utilizados 50 incisivos centrais superiores, divididos em 5 grupos, a saber: controle (só abertura coronária, clareamento sem calor, clareamento catalisado por calor controlado, clareamento catalisado por calor controlado e restauração com resina composta de última geração e dentes hígidos. Após o teste de cisalhamento, constatou-se que, nos dentes submetidos ao clareamento dental com perborato de sódio/Peridrol com ou sem aplicações de calor controlado, apesar de estes apresentarem leve diminuição da resistência ao cisalhamento, esta não é estatisticamente significante quando comparada com a dos dentes em que se executa o acesso endodôntico sem clareamento. A restauração do dente após o clareamento dental com adesivo dentinário de 4ª geração e resina fotopolimerizada aumenta a resistência do elemento dental clareado. Não existem diferenças estatísticas de resistência ao cisalhamento entre dentes clareados sem o uso de calor e aqueles em que o calor foi empregado de forma controlada, como preconizado neste estudo. Dentes hígidos apresentam resistência maior do que os dentes clareados com calor, sem calor e aqueles não clareados, com significância estatística no nível de 5%. Já com os dentes clareados e restaurados, os dentes hígidos não mostraram diferenças estatísticas significantes

    Full Text Available Foi avaliada a resistência de união entre dentes e base de dentadura, ambos de resina acrílica. Os dentes foram incluídos em blocos cilíndricos de resina e, posteriormente, torneados, para se obterem cilindros de 5mm de diâmetro. Sobre a extremidade do dente, era adaptado um padrão de cera de mesmo diâmetro, que, após inclusão na mufla, era substituído por resina acrílica termicamente ativada pelo método de processamento convencional de base de dentadura. Como variáveis, usaram-se duas marcas de dentes, duas fases de inclusão (plástica e borrachóide e aplicação ou não de detergente e monômero sobre os dentes. Os corpos-de-prova, antes dos ensaios de ruptura por tração, foram armazenados em água destilada, a 37ºC, por 2 semanas. Os resultados mostraram que: marca de dente e fase de condensação não influíram nos resultados; somente o uso de detergente ou de monômero aumenta a retentividade e o seu uso conjunto apresenta efeito acumulativo.

    Full Text Available Dens in dente, also known as dens invaginatus, dilated composite odontoma, or deep foramen caecum, is a developmental malformation that usually affects maxillary incisor teeth, particularly lateral incisors. It may occur in teeth anywhere within the jaws, other locations are comparatively rare. It can occur within both the crown and the root, although crown invaginations are more common. The use of cone beam computed tomography (CBCT is very helpful in endodontic diagnosis of complex anatomic variations. In this case we demonstrate the use of CBCT in the evaluation and endodontic management of a Type III dens in dente (Oehler′s Type III.

  18. Stress analysis of pressurized water reactor steam generator tube denting phenomena. Interim report

    International Nuclear Information System (INIS)

    Thomas, J.M.; Cipolla, R.C.; Ranjan, G.V.; Derbalian, G.

    1978-07-01

    In some Pressurized Water Reactor (PWR) steam generators, a corrosion product has formed on the carbon steel support plate in the crevice between the tube and support plate. The corrosion product occupies more volume than the original metal; the tube-to-support plate crevice volume is thus consumed with corrosion product, and further corrosive action results in a radially inward force on the tube and a radially outward force on the corroding support plate. This has resulted in indentation (''denting'') of the tube, accompanied by occasional cracking. Large in-plane deformation and cracking of support plates has also been observed in the most severely affected plants along with some serious side effects, such as deformation and cracking of inner row tube U-bends caused by support plate movement. Mechanical aspects of the tube denting phenomena have been studied using analytical models. The models used ranged from closed form analytical solutions to state-of-the-art numerical elastic-plastic computer program for moderate strains. It was found that tube dents, such as those observed in operating steam generators, are associated with yielding of both the tubes and support plates. Also studied were the stresses in tube U-bends caused by support plate flow slot deformation

    Full Text Available INTRODUÇÃO: As resinas compostas são materiais usualmente utilizados em restaurações dentárias diretas de dentes posteriores. O custo dos materiais faz parte do cálculo do valor dos honorários odontológicos. OBJETIVO: O objetivo deste trabalho foi determinar e analisar o valor total do custo dos materiais utilizados para a confecção de restaurações dentárias diretas de dentes posteriores em resina composta. MATERIAL E MÉTODO: O cálculo dos custos foi baseado no método de sistema de custeio variável. A lista dos materiais foi obtida por meio de consulta a uma banca de juízes e baseada nos padrões de excelência comprovados na literatura para atendimento em equipe. Os valores dos materiais foram obtidos de uma média dos valores consultados no mercado fornecedor. As repetições foram obtidas de preparos cavitários Classes I e II em dentes pré-molares e molares artificiais pré-fabricados. Os materiais foram quantificados para cada tipo de preparo. As resinas compostas utilizadas foram pesadas em balança de precisão após a sua inserção em cada tipo de preparo. Os dados foram avaliados por estatística descritiva e pelos testes de Mann-Whitney e Kruskal-Wallis. RESULTADO: O custo encontrado para restauração de Classe I foi de R$17,56 e, para a de Classe II, de R$17,73. Não houve diferença estatística no custo entre os tipos de preparo e de dentes, sendo a média total de R$17,65. CONCLUSÃO: Os valores encontrados podem ser utilizados no cálculo do valor final do procedimento restaurador, auxiliando na gestão de serviços odontológicos públicos ou privados.

    Full Text Available O Kerodon rupestris, também conhecido como mocó, é um roedor herbívoro encontrado no Brasil. A dentição dos mamíferos apresenta-se variável de acordo com as espécies embora seja formada pelos mesmos componentes: esmalte, dentina, cemento e polpa. Neste estudo foram utilizadas sete cabeças de Kerodon rupestris, adultos, de ambos os sexos. Na cavidade oral do Kerodon rupestris, devido ao tamanho relativamente grande dos incisivos, estes se destacaram dos demais e foram encontrados um par em cada mandíbula. Dois pares de pré-molares e três pares de molares foram encontrados, sendo representados na fórmula 2x (I 1/1, C 0/0, P 1/1, M 3/3. Os molares apresentaram duas cúspides, conformação que conferia a estes dentes um aspecto serrilhado. Microscopicamente os dentes incisivos, pré-molares e molares foram classificados como hipsodontes, ou seja, dentes em constante erupção.

    Full Text Available Palitos de dente são itens domésticos comuns e a maioria das pessoas subestima a gravidade das lesões que podem ocorrer com a ingestão acidental de palitos. Nós apresentamos um caso de abscesso perineal causado pela ingestão de um palito de dente. Um homem de 55 anos apresentou-se com quadro de dor perianal há um mês. Ao exame físico, notou-se abscesso perineal. Leucocitose com desvio à esquerda foi observada e a tomografia pélvica demonstrou um corpo estranho na região perineal. A remoção cirúrgica do corpo estranho e a drenagem adequada do abscesso foram realizadas, revelando um palito de dente. O paciente evoluiu bem após a abordagem cirúrgica. O abscesso perineal pode progredir para gangrena de Fournier e, portanto, a abordagem de abscessos perineais deve ser agressiva, com drenagem adequada e remoção do corpo estranho (sempre que presente.Toothpicks are a common household item and most people underestimate the seriousness of injuries that can occur with accidental ingestion. We report a case of a perineal abscess caused by an ingested toothpick. A 55-year-old man was admitted to the hospital with a 30-day history of perianal pain. Physical examination was unremarkable, except for a perineal abscess. Leucocytosis with 10% bands was present and pelvic tomography demonstrated a foreign body located in the perineal area. Surgical removal of the foreign body with adequate abscess drainage was performed revealing a toothpick. Perineal abscess may progress to Fournier's gangrene and as a consequence the management of a perineal abscess should be aggressive with adequate drainage and removal of the foreign body (if present.

    2018-01-01

    Full Text Available Mutations in the OCRL gene are associated with both Lowe syndrome and Dent-2 disease. Patients with Lowe syndrome present congenital cataracts, mental disabilities and a renal proximal tubulopathy, whereas patients with Dent-2 disease exhibit similar proximal tubule dysfunction but only mild, or no additional clinical defects. It is not yet understood why some OCRL mutations cause the phenotype of Lowe syndrome, while others develop the milder phenotype of Dent-2 disease. Our goal was to gain new insights into the consequences of OCRL exonic mutations on pre-mRNA splicing. Using predictive bioinformatics tools, we selected thirteen missense mutations and one synonymous mutation based on their potential effects on splicing regulatory elements or splice sites. These mutations were analyzed in a minigene splicing assay. Results of the RNA analysis showed that three presumed missense mutations caused alterations in pre-mRNA splicing. Mutation c.741G>T; p.(Trp247Cys generated splicing silencer sequences and disrupted splicing enhancer motifs that resulted in skipping of exon 9, while mutations c.2581G>A; p.(Ala861Thr and c.2581G>C; p.(Ala861Pro abolished a 5′ splice site leading to skipping of exon 23. Mutation c.741G>T represents the first OCRL exonic variant outside the conserved splice site dinucleotides that results in alteration of pre-mRNA splicing. Our results highlight the importance of evaluating the effects of OCRL exonic mutations at the mRNA level.

    2010-04-01

    Full Text Available O presente trabalho versa sobre o diagnóstico e a abordagem ortodôntica das anomalias dentárias, enfatizando os aspectos etiológicos que definem tais irregularidades de desenvolvimento. Parece existir uma inter-relação genética na determinação de algumas dessas anomalias, considerando-se a alta frequência de associações. Um mesmo defeito genético pode originar diferentes manifestações fenotípicas, incluindo agenesias, microdontias, ectopias e atraso no desenvolvimento dentário. As implicações clínicas das anomalias dentárias associadas são muito relevantes, uma vez que o diagnóstico precoce de uma determinada anomalia dentária pode alertar o clínico sobre a possibilidade de desenvolvimento de outras anomalias associadas no mesmo paciente ou em outros membros da família, permitindo a intervenção ortodôntica em época oportuna.This article aims to approach the diagnosis and orthodontic intervention of the dental anomalies, emphasizing the etiological aspects which define these developmental irregularities. It seems to exist a genetic inter-relationship determining some dental anomalies, considering the high frequency of associations. The same genetic defect may give rise to different phenotypes, including tooth agenesis, microdontia, ectopias and delayed dental development. The clinical implications of the associated dental anomalies are relevant, since early detection of a single dental anomaly may call the attention of professionals to the possible development of other associated anomalies in the same patient or in the family, allowing timely orthodontic intervention.

    Definition of the urinary protein composition would represent a potential tool for diagnosis in many clinical conditions. The use of new proteomic technologies allows detection of genetic and post-trasductional variants that increase sensitivity of the approach but complicates comparison within a heterogeneous patient population. Overall, this limits research of urinary biomarkers. Studying monogenic diseases are useful models to address this issue since genetic variability is reduced among first- and second-degree relatives of the same family. We applied this concept to Dent's disease, a monogenic condition characterised by low-molecular-weight proteinuria that is inherited following an X-linked trait. Results are presented here on a combined proteomic approach (LC-mass spectrometry, Western blot and zymograms for proteases and inhibitors) to characterise urine proteins in a large family (18 members, 6 hemizygous patients, 6 carrier females, and 6 normals) with Dent's diseases due to the 1070G>T mutation of the CLCN5. Gene ontology analysis on more than 1000 proteins showed that several clusters of proteins characterised urine of affected patients compared to carrier females and normal subjects: proteins involved in extracellular matrix remodelling were the major group. Specific analysis on metalloproteases and their inhibitors underscored unexpected mechanisms potentially involved in renal fibrosis. Studying with new-generation techniques for proteomic analysis of the members of a large family with Dent's disease sharing the same molecular defect allowed highly repetitive results that justify conclusions. Identification in urine of proteins actively involved in interstitial matrix remodelling poses the question of active anti-fibrotic drugs in Dent's patients. Copyright © 2015 Elsevier B.V.

    Emotion psychology makes it clear that where there is psychology activity, there is emotion. And it also holds people’ whole real life. Emotion not only instigates human’s instinctive activities but also affects his social study and creative power. It is our motive power to act, so we can’t ignore this unintelligent factor-emotion in our English study . It directly affects the stu-dents when their integrative motivation is being fostered and for-mal. So,the author mainly states we should pay more attention to the emotion factors in our English teaching , keeping the stu-dents’ emotion healthy and optimistic, and discusses what we can do to hold the students’ emotion ,guide their learning motivation and developing the students’ interest in English. In a word, the teaching pattern of interaction between emotion and knowledge gets the students to gain the knowledge in a relaxing and pleasant teaching atmosphere and moulds the students’ feeling.

    Full Text Available OBJECTIVES: The aim of this study was to evaluate the influence of remaining coronal tooth structure on endodontically treated teeth restored with prefabricated posts and two different composites for core build-up: dual-cured resin (Enforce Core and light-cured resin (Z-250. METHODS: Fourty freshly extracted canines were endodontically treated and divided into four groups: Group I - teeth with 3mm remaining coronal structure, restored with Enforce Core; Group II - teeth with 3mm remaining coronal structure, restored with Z-250; Group III - teeth with no remaining coronal structure, restored with Enforce; Group IV - teeth with no remaining coronal structure, restored with Z-250. After restoration, the teeth were embedded in acrylic resin and the fracture resistance was measured on a universal testing machine at 45 degrees to the long axis of the tooth until failure. RESULTS: Data were analyzed by two-way analysis of variance, which showed significant differences between groups (p=0.00. The Tukey test did not show significant differences between specimens with and without remaining coronal structure. Conversely, significant difference was observed between groups with different core build-up. The highest values of fracture resistance were found in the group restored with light-cured resin. SIGNIFICANCE: The remaining coronal tooth structure did not influence the resistance of endodontically treated teeth; however, the change of core build-up was able to modify this resistence.O objetivo desta pesquisa foi avaliar a influência do remanescente dentário coronal de dentes tratados endodonticamente, restaurados com pinos pré-fabricados e duas resinas como núcleos de preenchimento, uma de presa dual (Enforce Core e outra fotopolimerizável (Z-250.

    We consider a deformation of the well-known stu model of N=2, D=4 supergravity, characterized by a non-homogeneous special Kähler manifold, and by the smallest electric-magnetic duality Lie algebra consistent with its upliftability to five dimensions. We explicitly solve the BPS attractor equations and construct static supersymmetric black holes with radial symmetry, in the context of U(1) dyonic Fayet-Iliopoulos gauging, focussing on axion-free solutions. Due to non-homogeneity of the scalar manifold, the model evades the analysis recently given in the literature. The relevant physical properties of the resulting black hole solution are discussed.

    2015-01-01

    Polyuria after kidney transplantation causes graft dysfunction and increased thrombotic risk. We present a case of a polyuric adult with Dent's disease who underwent staged bilateral native nephrectomies, the first operation before transplant and the second four months after transplant. This led to improved allograft function maintained during four years of follow-up. The retroperitoneal laparoscopic approach was well tolerated and allowed continuation of peritoneal dialysis before transplantation. A staged approach helps regulate fluid balance perioperatively and may be tailored to individual need according to posttransplant urine output. This novel approach should be considered for polyuric patients with tubular dysfunction including Dent's disease. PMID:25649339

    Full Text Available Realizou-se um estudo anatômico em dentes do Cebus apella, para análise da anatomia interna do canal radicular dessa espécie, normatizando seu uso como modelo experimental. Utilizaram-se doze animais adultos. Após a remoção do tecido orgânico, os dentes foram removidos, seccionados e fotografados, sendo analisados com um estereomicroscópio. Os resultados mostraram que os dentes apresentaram características semelhantes às dos seres humanos, mas com algumas peculiaridades, tais como: a anatomia do canal radicular variou de oval para circular; nos caninos inferiores, os canais são semelhantes a um rim, o que reflete o contorno externo da raiz; nos molares superiores, os canais mesiobucal e distobucal são ovais, seguindo o contorno geral do dente. Os autores concluem que esta espécie pode ser utilizada como modelo em pesquisas odontológicas, principalmente em estudos do tratamento do sistema de canal radicular.

    PALAVRAS-CHAVES: Anatomia, dentes, Cebus apella. An anatomic study of Cebus apella root teeth was performed to analyze the internal anatomy of permanent dentition, normalizing its use as experimental model endodontic research. Twelve adult animals were used in this study. After the removal of the organic tissue, the all teeth were removed, sectioned, analyzed and photographed with a stereomicroscope. The results showed that the anatomy of root canal of this species are similar to human dental anatomy, considering the shape, pathway and number of canals, but with some peculiarities, such as: the root canal anatomy varied from oval to circular; in the lower canines, the canals are resembled a kidney, reflecting the outside contour of the root; in the upper molars, the mesiobuccal and distobuccal canals are oval, following the general contour of the tooth. The authors conclude that this primate can be applied as models for study of root canal treatment in human beings, in special the upper central and lateral incisors

    Full Text Available Generally, different students employ different learning styles dur-ing their studies and medical students are exposed to diverse methods of teaching. Therefore, understanding students’ learning style preference is an important consideration for a high quality and effective teaching and learning process.The aim of the study was to study the variation of learning styles among pre-clinical medical students of SEGi University, Malaysia. A cross-sectional study was performed by using VARK (Visual, Audio, Reading and Kinaesthetic questionnaire version 7.2 to assess the learning style preference of 98 (n=98 pre-clinical medical students in SEGi University. The questionnaire consists of 16 items which identify four different learning styles: visual, aural, reading/writing and kin-esthetic. Descriptive statistics were used to identify the learning styles of students. 61 students preferred multimodal as their learning style, out of which 43 (70% of them were female stu-dents and 18 (30% were male students. 37 students preferred unimodal as their learning style out of which 22 (59% of them were female students and 15 (41% were male students. In addi-tion, female students had more diverse preferences than male students by having 10 out of the other 11 possible combinations in multimodal learning style of preference, whereas the male stu-dents only had 5 out of the 11 combinations. In this study, there was no significant gender difference in the percentages of males and female students who preferred unimodal and multimodal styles of information presentation (P= 0.263; α=0.05. To con-clude, the majority of students of both genders had chosen quad-modal as their learning style preference.

    Full Text Available INTRODUÇÃO: a maneira como a cárie dentária é conceituada e seus fatores etiológicos considerados têm gerado divergências, na elaboração de estratégias preventivas, entre epidemiologistas e profissionais da saúde. As considerações e o conhecimento sobre a formação, progressão e definição da lesão de cárie devem ser aprofundados, para se estabelecer critérios que favoreçam o diagnóstico, a prevenção e o tratamento, preservando a qualidade de vida do paciente. O conceito de cárie dentária como doença infecciosa, transmissível e dieta dependente deve ser revisto, e os fatores etiológicos melhor interpretados e entendidos, para evitar estratégias de prevenção e tratamento equivocadas. É necessário um posicionamento mais conclusivo de instituições científicas e universidades, objetivando o estabelecimento definitivo desses conceitos, para que possam refletir-se em resultados práticos. OBJETIVO: o objetivo deste trabalho foi trazer uma contribuição baseada em 35 anos de exercício profissional e da vivência acadêmica no ensino e pesquisa e, também, realizar uma revisão da literatura de Cariologia, com a intenção de levar a uma interpretação dos achados científicos que permita um raciocínio lógico sobre o conceito de cárie dentária e dos fatores envolvidos em sua etiologia, podendo, com isso, chegar o mais próximo possível da verdade. RESULTADOS E CONCLUSÕES: os conhecimentos adquiridos até hoje, por meio da pesquisa científica e também a partir das conclusões deste trabalho, permitem elaborar estratégias preventivas mais eficientes em todo o planeta e a cárie dentária passará a ser, dentro de pouco tempo, um problema irrelevante ao ser humano. A partir do raciocínio desenvolvido neste trabalho, pode-se concluir que a cárie dentária não deve ser considerada uma doença, mas simplesmente uma lesão do esmalte de causa local, sem fatores etiológicos determinantes, porém provocada

    The fungal pathogen Fusarium verticillioides infects maize ears and produces fumonisins, known for their adverse effects on human and animal health. Basic questions remain unanswered regarding the kernel stage(s) associated with fumonisin biosynthesis and the kernel components involved in fumonisin regulation during F. verticillioides-maize interaction under field conditions. In this 2-year field study, the time course of F. verticillioides growth and fumonisin accumulation in developing maize kernels, along with the variations in kernel pH and amylopectin content, were monitored using relevant and accurate analytical tools. In all experiments, the most significant increase in fumonisin accumulation or in fumonisin productivity (i.e., fumonisin production per unit of fungus) was shown to occur within a very short period of time, between 22/32 and 42 days after inoculation and corresponding to the dent stage. This stage was also characterized by acidification in the kernel pH and a maximum level of amylopectin content. Our data clearly support published results based on in vitro experiments suggesting that the physiological stages of the maize kernel play a major role in regulating fumonisin production. Here we have validated this result for in planta and field conditions, and we demonstrate that under such conditions the dent stage is the most conducive for fumonisin accumulation. PMID:21984235

    2014-01-01

    Full Text Available A avulsão é um traumatismo dentário de graves consequências para o dente permanente pelo dano que pode ocorrer à estrutura periodontal. O reimplante imediato deve ser o tratamento de eleição, porém muitas vezes não é possível, e o sucesso do futuro reimplante dependerá do tempo em que o dente permanece fora do alvéolo e o meio no qual ele é mantido. O objetivo deste trabalho é fazer uma revisão da literatura sobre os meios de conservação devido a sua importância no prognóstico do reimplante. Embora muitos meios venham sendo testados, até o momento nenhum deles preenche todos os requisitos biológicos e ainda esteja disponível no local do acidente. A saliva e a água, embora sejam de fácil acesso, têm demonstrado causar efeitos deletérios nas células do ligamento periodontal. Apesar dos seus efeitos biológicos positivos, os meios de cultura raramente estão ascessíveis no local do acidente, o que torna seu uso impraticável. A própolis e o extrato de chá verde parecem ser promissores e novos estudos ainda precisam ser realizados. O leite, em especial o longa vida desnatado, parece ser uma boa opção, pois apresenta bons resultados com relação à viabilidade celular e costuma estar disponível

    Full Text Available This anthropological study critically evaluates Brazilian caregivers' symbolic production and significance of their malnourished offspring's primary teeth, as well as their own, and describes popular dental practices. From January to June 2004, ethnographic interviews of 27 poor, low-literacy mothers were conducted at a public Malnutrition Treatment Center in Fortaleza, Ceará State. Participant observation of clinical pathways and home environments supplemented the data. Content analysis was performed. Results confirm that primary teeth are imbued with cultural significance in Northeast Brazil. Mothers examine mouths, perceive signs of decay, associate primary with permanent tooth healthiness, identify ethnodental illnesses, seek assistance, and perform rituals with exfoliated teeth. The mother's motivation to care for primary teeth is sparked by her memories of past toothache and attempts to avoid stigma and discrimination. Social determinants, not mothers' beliefs or behaviors, are the most critical obstacles to effective dental care. Legitimizing lay knowledge and empowering caregivers and children can improve oral health in Northeast Brazil.Este estudo antropológico analisa a produção simbólica de cuidadoras brasileiras sobre a sua dentição e a de seus filhos desnutridos, descrevendo práticas populares de cuidados em saúde bucal.

    2010-08-01

    Full Text Available INTRODUÇÃO: a alta prevalência de indivíduos com traumatismo dentário prévio ao tratamento ortodôntico justifica os cuidados a serem observados antes e durante o tratamento, considerando todas as implicações do movimento ortodôntico sobre os dentes traumatizados. Entre as lesões traumáticas dentárias, a avulsão com posterior reimplantação do dente é a que apresenta maior risco de complicações - como necrose pulpar, reabsorção radicular e anquilose -, sendo também a que inspira maiores cuidados pelo ortodontista. OBJETIVO: este trabalho busca, através do relato de um caso clínico, analisar as implicações do reimplante dentário após avulsão traumática, em pacientes que requerem tratamento ortodôntico. CONCLUSÕES: a movimentação ortodôntica de um dente reimplantado, após sua avulsão traumática, é possível desde que não ocorra qualquer sinal de anormalidade. Porém, dentes que sofrem anquilose não são passíveis de movimentação ortodôntica, mas devem ser preservados como mantenedores de espaço, até a reabsorção total da raiz, desde que não apresentem infraposição severa. Ocorrendo infraposição severa do dente anquilosado, é indicada a amputação da coroa e o sepultamento da raiz, como meio de favorecer a manutenção do osso alveolar na região, pois ocorrerá reabsorção por substituição da raiz sepultada, como ocorreu no caso clínico apresentado.INTRODUCTION: The high prevalence of individuals with dental trauma prior to orthodontic treatment justifies the precautions that should be followed before and during treatment, considering all possible effects of orthodontic movement on traumatized teeth. Among the major traumatic dental injuries, avulsion with subsequent tooth reimplantation entails a higher than average risk of complications, such as pulp necrosis, root resorption and ankylosis. Therefore, it gives orthodontists several reasons for concern. OBJECTIVE: This case report sought

Para sua mensuração têm sido formulados índices que consideram a quantidade e intensidade de placa bacteriana (PB e de cálculo dental (CD existentes na superfície dentária por meio de avaliação visual subjetiva. O presente estudo tem como objetivo avaliar o método de análise computadorizada para medição de área de PB e CD nos dentes de cães através da comparação com a avaliação visual. Foram utilizados 10 cães Beagles, três machos e sete fêmeas, com similares características e mantidos sob o mesmo manejo e dieta alimentar. As avaliações das superfícies vestibulares dos dentes ocorreram antes da profilaxia dentária, que foi realizada sob anestesia geral inalatória, e após sete dias para PB e após 28 dias para CD. A avaliação computadorizada da área de CD demonstrou ser estatisticamente melhor em relação à avaliação visual antes e após a profilaxia; entretanto, não demonstrou diferença significante na avaliação da PB. Concluiu-se que a avaliação computadorizada é vantajosa em relação à visual por conferir maior precisão na obtenção da proporção entre área total do dente e área acometida, mostrando-se estatistticamente superior na quantificação do CD após 28 dias.Periodontal disease is caused by dental plaque accumulation on teeth and adjacent structures.

Foram selecionados trinta molares superiores recém-extraídos, dez para cada condição experimental. Uma liga do sistema prata/estanho (M3 foi utilizada para obtenção das coroas totais. As amostras foram submetidas a ciclagens térmicas nas temperaturas de 5ºC, 37ºC e 55ºC, por sessenta minutos, durante sete dias. Para a última ciclagem térmica, foi utilizado o corante Rhodamina B a 0,1%, em solução aquosa. A seguir, as amostras foram lavadas e mantidas em condições ambientais por vinte e quatro horas, para serem levadas à máquina de ensaios universal, para os testes de remoção por tração axial. A análise de variância mostrou diferença estatisticamente significante, no nível de 5%, dos dentes sem reconstrução (controle, com relação aos dentes reconstruídos com "mistura milagrosa" e dentes reconstruídos com Cermet. Os dentes sem reconstrução apresentaram maior média aos testes de resistência por tração. Verificou-se, pela comparação individual entre as condições avaliadas, que o grupo reconstruído com "mistura milagrosa" e Cermet não mostrou diferença estatisticamente significante. Da mesma forma, foram elaboradas comparações individuais entre as condições avaliadas dos escores de infiltração, em que se pôde observar que houve significância entre os grupos de "mistura milagrosa" e Cermet com o grupo controle (dentes sem reconstrução. Os dentes reconstruídos com "mistura milagrosa" e Cermet não mostraram diferenças estatisticamente significantes entre siThe aim of this work was to measure tensile

    Full Text Available INTRODUCTION: Over the last two decades, the prevalence of dental caries in children has decreased and the prevalence of dental fluorosis has increased. Knowledge on the epidemiologic conditions of a population is fundamental for the planning of health programs. OBJECTIVES: To determine the prevalence of dental caries and dental fluorosis among schoolchildren, in Catalão, Goiás, Brazil. METHODS: A random sample of 432 schoolchildren aged 7-12-years old was obtained. WHO (1997 criteria for dental caries and fluorosis diagnosis were used. RESULTS: The DMFT indexes were 0.97; 1.20; 1.80; 1.62; 2.40 and 2.51 for 7, 8, 9, 10, 11 and 12 years old, respectively. Analysis of dental fluorosis for the same ages presented higher prevalence at 12 years old and for the female gender. The percentage of questionable dental fluorosis (Dean's classification was 34.0%. Only 3% of the sample presented dental fluorosis with scores very mild, mild and moderate. CONCLUSIONS: The prevalence of caries in schoolchildren of Catalão, Goiás, Brazil, was low. In average, private schools showed better results than public schools; however, all schools presented a low DMFT index. In this study, dental fluorosis is not a public health problem and has not damaged dental esthetics.INTRODUÇÃO: Nas últimas duas décadas, a prevalência de cárie dentária tem diminuído e a prevalência de fluorose dentária tem aumentado.

    Effective approaches for teaching vocabulary to various populations of learners is a topic of current research (Barr, Eslami, & Malatesha, 2012) yet little research is dedicated to students with learning disabilities in the science classroom. Within this study the interac-tive word wall was used as a tool to build vocabulary and to encourage usage of new sub-ject-specific terminology. The experiment utilized quasi-experimental pre-post test com-parison group design using interrupted time-series (Johnson & Christiensen, 2007) due to the inability to randomize participants and establish a clear control group. The data was collected across four units of terminology and with a student satisfaction survey. Stu-dents reported at least seventy percent satisfaction with the use of Interactive Word Walls and demonstrated some performance increase in both vocabulary retention and reading comprehension when utilizing Interactive Word Walls.

  11. The impacts and "best practices" of undergraduate - graduate student mentoring relationships in undergraduate research experiences

    Science.gov (United States)

    Campanile, Megan Faurot

    With the growth of undergraduate research in the U.S., over the past two decades, faculty are more often assigning graduate students to mentor undergraduate students than providing the one-on-one mentoring themselves. A critical gap that exists in the literature is how undergraduate -- graduate student mentoring relationships in undergraduate research influences both students' academic and career paths. The research questions that framed this study were: (1) What, if any, changes occur in the academic and career paths of undergraduate and graduate students who participate in undergraduate research experiences? and (2) Are there variables that constitute "best practices" in the mentoring relationships in undergraduate research experiences and, if so, what are they? The study context was the National Science Foundation Research Experiences for Undergraduates program at Illinois Institute of Technology and the 113 undergraduate researchers and 31 graduate student mentors who participated from 2006 -- 2014. Surveys and interviews were administered to collect pre- and post-program data and follow-up data during the 2014 -- 2015 academic year. Descriptive statistics, content analysis method, and constant comparative method were used to analyze the data. Key findings on the undergraduate researchers were their actual earned graduate degree types (Ph.D. 20%, M.D. 20%, M.S. 48%, other 12%) and fields (STEM 57%, medical 35%, other 8%) and the careers they were pursuing or working in. All the graduate student mentors were pursuing or working in the STEM fields (academia 50%, industry 40%, government 10%). More than 75% of both the undergraduate and graduate students reported that their mentoring relationships had a somewhat to extremely influential impact on their academic and career paths. A set of "best practices" of mentoring were developed for both the undergraduate and graduate students and focused on the mentoring experiences related to learning and teaching about

    Full Text Available OBJECTIVE: This study aimed to evaluate the prevalence of developmental defects of enamel (DDEs in relation to asthma severity, symptom onset and pharmacological treatment in pediatric asthma patients. METHODS: Children and adolescents (68 asthma patients and 68 controls, 5-15 years of age and residents of the city of Londrina, Brazil, were enrolled in the study. Medical and dental histories were collected through the use of a structured questionnaire. Each participant underwent a dental examination in which the examiner employed the DDE index. RESULTS: Of the 68 asthma group subjects, 61 (89.7% presented dental enamel defects, compared with only 26 (38.2% of those in the control group. Using multivariate logistic regression analysis, we estimated the risk of DDEs in permanent dentition to be 11 times higher in pediatric subjects with asthma than in those without (OR = 11.88, p = 0.0001. The occurrence of dental enamel defects correlated with greater asthma severity (p = 0.0001 and earlier symptom onset (p = 0.0001. However, dental enamel defects did not correlate with the initiation of treatment (p = 0.08 or the frequency of medication use (p = 0.93. CONCLUSIONS: Pediatric patients with severe, early-onset asthma are at increased risk of dental enamel defects and therefore require priority dental care.OBJETIVO: Avaliou-se a prevalência de developmental defects of enamel (DDEs, defeitos de desenvolvimento do esmalte dentário em pacientes pediátricos com asma e sua relação com a severidade da asma, o início dos sintomas e o tratamento medicamentoso.

    Undergraduate research is a valuable educational tool for students pursuing a degree in physics, but these experiences can become problematic and ineffective if not handled properly. Undergraduate research should be planned as an immersive learning experience in which the student has the opportunity to develop his/her skills in accordance with their interests. Effective undergraduate research experiences are marked by clear, measurable objectives and frequent student-professor collaboration. These objectives should reflect the long and short-term goals of the individual undergraduates, with a heightened focus on developing research skills for future use. 1.

    Full Text Available São relatados três casos de conjuntivite bacteriana associada à doença dentária grave em chinchilas. Todas as chinchilas afetadas tinham histórico de emagrecimento, hipersalivação e epífora, que progrediu para exsudação ocular purulenta. Durante a necropsia, foi constatado marcado alongamento da coroa clínica dos incisivos e molares, e crescimento do ápice dentário, causando deformação óssea e compressão do canal lacrimal. Histologicamente, observou-se infiltrado de neutrófilos na conjuntiva e pálpebras. Cultivo microbiológico do exsudato ocular revelou crescimento de Staphylococcus coagulase-positiva . Uma compressão do canal lacrimal pelo crescimento dentário excessivo impediu a drenagem das lágrimas, resultando em epífora. Esse é um importante fator predisponente para infecção bacteriana ocular em chinchilas.Three cases of bacterial conjunctivitis associated with severe dental disease in chinchillas are described. All affected chinchillas had a history of weight loss, ptyalism, and epiphora which progressed to suppurative ocular exsudation. At necropsy incisor and molar teeth revealed marked elongation of the clinical crown and overgrowth of the dental apexes resulting in deformation of the tear ducts. Histologically, there was neutrophilic infiltrate in the conjunctiva and eyelid skin. Microbiological culture carried out in samples from the ocular exsudate yielded Staphylococcus coagulase-positive. Compression of the lacrimal duct by dental overgrowth compromised tear draining and resulting in epiphora. This is a major predisposing factor inducing bacterial ocular infection in chinchillas.

    Undergraduate research is a proven effective pedagogy that has a number of benefits including: enhancing student learning through mentoring relationships with faculty; increasing retention; increasing enrollment in graduate programs; developing critical thinking, creativity, problem solving and intellectual independence; and, developing an understanding of research methodology. Undergraduate research also has been demonstrated in preparing students for careers. In addition to developing disciplinary and technical expertise, participation in undergraduate research helps students improve communication skills (written, oral, and graphical) and time management. Early involvement in undergraduate research improves retention and, for those engaged at the 2YC level, helps students successfully transfers to 4YC. The Geosciences Division of the Council on Undergraduate Research (GeoCUR) supports faculty in their development of undergraduate research programs at all levels. GeoCUR leads workshops for new and future faculty covering all aspects of undergraduate research including incorporating research into coursework, project design, mentoring students, sustaining programs, and funding sources. GeoCUR members support new faculty by providing a range of services including: peer-review of grant proposals; advice on establishing an undergraduate research program; balancing teaching and research demands; and networking with other geoscientist. GeoCUR has also developed web resources that support faculty and departments in development of undergraduate research programs (http://serc.carleton.edu/NAGTWorkshops/undergraduate_research/index.html). This presentation will describe the services provided by GeoCUR and highlight examples of programs and resources available to geoscientists in all career stages for effective undergraduate research mentoring and development.

    There has been a growing concern in higher education about our failure to produce scientifically trained workers and scientifically literate citizens. Active-learning and research-oriented activities are posited as ways to give students a deeper understanding of science. We report on an undergraduate teaching assistant (UTA) experience and suggest that students who participate as a UTA obtain benefits analogous to those who participate as an undergraduate research assistant (URA). We examined the experiences of 24 undergraduates acting as UTAs in a general microbiology course. Self-reported gains by the UTAs were supported by observational data from undergraduates in the course who were mentored by the UTAs and by the graduate teaching assistants (GTAs) with whom the UTAs worked. Specifically, data from the UTAs’ journals and self-reported Likert scales and rubrics indicated that our teaching assistants developed professional characteristics such as self-confidence and communication and leadership skills, while they acquired knowledge of microbiology content and laboratory skills. Data from the undergraduate Likert scale as well as the pre- and post-GTA rubrics further confirmed our UTA’s data interpretations. These findings are significant because they offer empirical data to support the suggestion that the UTA experience is an effective option for developing skills and knowledge in undergraduates that are essential for careers in science. The UTA experience provides a valuable alternative to the URA experience. PMID:23653688

    Full Text Available The dentifrices currently available in the marketplace contain many anticariogenic substances, fluoride and abrasives aimed to better clean the dental surface, remove dental plaque, improve salivary flow and its buffer capacity and reduce colonies of bacteria such as S. mutans, the causative agent of dental caries. The objective of this study was to evaluate the possibility of adequately removing dental plaque using an experimental almond oil dentifrice (Titoil with no abrasives or antiplaque agents. This study was carried out with 80 volunteers, all of them 18-year-old recruits from the military training school of Araçatuba - SP. Saliva sampling and dental plaque disclosing were undertaken both before and after 28 days of toothbrushing with a low abrasive dentifrice (Group 1: 40 volunteers or with Titoil (Group 2: 40 volunteers. Statistical analysis of the results revealed that the experimental dentifrice (Titoil did not interfere with salivary flow and reduced dental plaque more than the low abrasive dentifrice, improved the salivary buffer capacity and decreased salivary S. mutans (Caritest-SM as much as regular dentifrices. It was concluded that if the dental industry replaces abrasive by vegetable oil in dentifrices, these will be more effective in maintaining oral health and will cause less dental abrasion.Os dentifrícios atualmente encontrados no mercado contêm muitas substâncias anticariogênicas, flúor e abrasivos para higienizar melhor as superfícies dentárias, remover a placa dentária, melhorar o fluxo salivar e a capacidade tampão e reduzir as colônias bacterianas, como de S. mutans, agente causador da cárie dentária.

    The NSF-sponsored Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team (UAT) is a consortium of 19 institutions founded to promote undergraduate research and faculty development within the extragalactic ALFALFA HI blind survey project and follow-up programs. In this talk we present outcomes for the more than 250 undergraduate students who have who have participated in the program during the 8 years of funding. 40% of these students have been women and members of underrepresented groups. To date 148 undergraduate students have attended annual workshops at Arecibo Observatory, interacting with faculty, graduate students, their peers, and Arecibo staff in lectures, group activities, tours, and observing runs. Team faculty have supervised 159 summer research projects and 120 academic year (e.g., senior thesis) projects. 68 students have traveled to Arecibo Observatory for observing runs and 55 have presented their results at national meetings such as the AAS. Through participation in the UAT, students are made aware of career paths they may not have previously considered. More than 90% of alumni are attending graduate school and/or pursuing a career in STEM. 42% of those pursuing graduate degrees in Physics or Astronomy are women.

    2018-01-01

    Full Text Available Objectives: This research brief explores the literature addressing quality in undergraduate education to identify what previous research has said about quality and to offer future directions for research on quality in undergraduate education. Method: We conducted a scoping review to provide a broad overview of existing research. Using targeted search terms in academic databases, we identified and reviewed relevant academic literature to develop emergent themes and implications for future research. Results: The exploratory review of the literature revealed a range of thoughtful discussions and empirical studies attempting to define quality in undergraduate education. Many publications highlighted the importance of including different stakeholder perspectives and presented some of the varying perceptions of quality among different stakeholders. Conclusions: While a number of researchers have explored and written about how to define quality in undergraduate education, there is not a general consensus regarding a definition of quality in undergraduate education. Past research offers a range of insights, models, and data to inform future research. Implication for Theory and/or Practice: We provide four recommendations for future research to contribute to a high quality undergraduate educational experience. We suggest more comprehensive systematic reviews of the literature as a next step.

    Full Text Available This study examines the empirical link between three dimensions of market orientation, namely, stu­dent orientation, competitor orientation and inter-functional coordination, and overall private uni­ver­sity per­formance in Kopertis X. It was based on an empirical investigation of private universities located in In­do­nesia’s provinces of West Sumatera, Riau, Jambi, and Kepulauan Riau. The primary data for the study were collected from a self-administered mail survey of 237 questionnaires from the private university re­sul­­ting in a sample of 114 usable responses being returned. From the application of the multiple re­gres­sion ana­lysis it was concluded that all three dimensions of market orientation had a significant impact on private un­iversity performance. Student orientation as a predictor variable is the strongest predictor of pri­vate uni­ver­­sity performance and followed by competitor orientation, and inter-functional coordination.

  6. A Social Capital Perspective on the Mentoring of Undergraduate Life Science Researchers: An Empirical Study of Undergraduate-Postgraduate-Faculty Triads.

    2016-01-01

    Undergraduate researchers at research universities are often mentored by graduate students or postdoctoral researchers (referred to collectively as "postgraduates") and faculty, creating a mentoring triad structure. Triads differ based on whether the undergraduate, postgraduate, and faculty member interact with one another about the undergraduate's research. Using a social capital theory framework, we hypothesized that different triad structures provide undergraduates with varying resources (e.g., information, advice, psychosocial support) from the postgraduates and/or faculty, which would affect the undergraduates' research outcomes. To test this, we collected data from a national sample of undergraduate life science researchers about their mentoring triad structure and a range of outcomes associated with research experiences, such as perceived gains in their abilities to think and work like scientists, science identity, and intentions to enroll in a PhD program. Undergraduates mentored by postgraduates alone reported positive outcomes, indicating that postgraduates can be effective mentors. However, undergraduates who interacted directly with faculty realized greater outcomes, suggesting that faculty interaction is important for undergraduates to realize the full benefits of research. The "closed triad," in which undergraduates, postgraduates, and faculty all interact directly, appeared to be uniquely beneficial; these undergraduates reported the highest gains in thinking and working like a scientist. © 2016 M.

  7. Central and peripheral nervous complications of dental treatment Complicações de tratamento dentário afetando o sistema nervoso

    Eva Olovsson Rossitti

    1995-09-01

    Full Text Available This review outlines the complications involving the central or peripheral nervous system arising from dental procedures reported in the last decade. By far the commonest complications were related to intraoperative mechanical peripheral nerve injury. Trauma to branches of the mandibular nerve occuring during oral operations may potentially result in varying degrees of hypoesthesia, paresthesia, dysesthesia or in chronic pain syndromes. An increase in malpractice suits related to such a complication has been recognized in the late years. A warning of the possibility of occurrence of this complication should to be given to all patients undergoing risky procedures as part of the process of obtaining informed consent to operation. Mandibular third molar extraction seems to be alone the most hazardous procedure related to mechanical nerve injuries and also with anesthesiological accidents. Severe but rather infrequent infectious (meningitis, brain abscess and cavernous sinus thrombophlebitis and anesthesiological complications (occular and facial palsies, optic nerve injury and complications related to general anesthesia were also reported in this period.Complicações, ou eventos inesperados e indesejáveis associados a terapia de uma dada condição, podem ser particularmente incapacitantes quando afetam o sistema nervoso.

  9. Teaching and Research at Undergraduate Institutions

    2006-03-01

    My own career path has been non-traditional and I ended up at a primarily undergraduate institution by pure accident. However, teaching at a small college has been extremely rewarding to me, since I get to know and interact with my students, have an opportunity to work with them one-on-one and promote their intellectual growth and sense of social responsibility. One of the growing trends at undergraduate institutions in the past decade has been the crucial role of undergraduate research as part of the teaching process and the training of future scientists. There are several liberal arts institutions that expect research-active Faculty who can mentor undergraduate research activities. Often faculty members at these institutions consider their roles as teacher-scholars with no boundary between these two primary activities. A researcher who is in touch with the developments in his/her own field and contributes to new knowledge in the field is likely to be a more exciting teacher in the classroom and share the excitement of discovery with the students. At undergraduate institutions, there is generally very good support available for faculty development projects in both teaching and research. Often, there is a generous research leave program as well. For those who like advising and mentoring undergraduates and a teaching and learning centered paradigm, I will recommend a career at an undergraduate institution. In my presentation, I will talk about how one can prepare for such a career.

  10. 'Dented' and 'resuscitated' masculinities: the impact of HIV diagnosis and/or enrolment on antiretroviral treatment on masculine identities in rural eastern Uganda.

    Science.gov (United States)

    Siu, Godfrey E; Wight, Daniel; Seeley, Janet

    2014-01-01

    There is limited research on the impact of HIV or its treatment on men's identity construction and gender roles in sub-Saharan Africa. Based on in-depth research with 26 men in rural Uganda, this article discusses men's vulnerabilities and shifting gender relations and sense of masculinity resulting from HIV infection or enrolment on treatment in eastern Uganda. The findings suggest two broad categories of masculinity: respectable and reputational. HIV infection and illness dented masculinity as men lost authority within the domestic sphere. A weakened provider role and over-reliance on wives and children undermined masculinity as family head, and social sanctioning of their sexual activity, undermined conventional masculine identities predicted on reputation. However, treatment led to a more reflexive approach to demonstrating masculinity, increased attentiveness to health and restored hope to father children free of HIV, resuscitating respectable masculinities. The balance between eroded and restored masculinity varied between men by their treatment history, age, family composition and state of health. HIV support agencies need to pay attention to the way HIV and antiretroviral treatment (ART) influence men's perception of their masculinity and support them to overcome the anxieties about dented or eroded masculinity, while building on the positive ways in which treatment restores masculinity to support men's adherence to HIV treatment. In particular, there is a need to support men's engagement in productive activities that bring income so that men can regain their provider roles following ART and restore their respectability in both the public and the domestic sphere.

  11. Probe for detection of denting in PWR steam generator tubes; Sonde de detection du denting des tubes de generateurs de vapeur REP

    Energy Technology Data Exchange (ETDEWEB)

    Gerardin, J P; Germain, J L; Nio, J C

    1994-07-01

    In certain types of PWR steam generator, oxide deposits can lead to embedding, and subsequently to deformation of a tube (the phenomenon of ``denting``). Such embedding changes the vibratory behavior of the tubes and can result in fatigue cracking. This type of cracking can also be worsened in the event of improper assembly of the anti-vibration spacer bars supporting the U-bends. To prevent such incidents and provide for effective preventive condition-directed maintenance of its PWR steam generators, EDF has undertaken the study and development of a probe to detect this type of phenomenon. The studies began in 1990 and led to the building of an initial prototype probe. The principle behind the probe consists in inducing vibration in the U-bend and determining the main resonance modes of the tube. Measurements of frequency and amplitude and calculation of damping enable characterization of the mechanical behavior of the U-bend. The most important parameter is damping, for which the value must be sufficiently high to ensure that the tube is not subjected to major vibratory amplitudes during operation. Numerous tests have been performed with the first prototype version of the probe, on a mock-up in the test area and on one of the demounted steam generators on the Dampierre site. These different tests have enabled validation of the operating principle, fine-tuning the process, pinpointing certain mechanical problems in the probe design, and obtaining the first indications as to the real vibratory behavior of U-bends on a steam generator. On the basis of these preliminary tests, the specifications were drawn up for an industrial version of the probe. Following a call for bids and the choice of a manufacturer, work began on fabrication of a new probe model in 1993. This version was delivered at the end of 1993 and testing began in 1994.

    Han, Deguang; Larson, David; Weber, Eric

    2007-01-01

    Frames for Undergraduates is an undergraduate-level introduction to the theory of frames in a Hilbert space. This book can serve as a text for a special-topics course in frame theory, but it could also be used to teach a second semester of linear algebra, using frames as an application of the theoretical concepts. It can also provide a complete and helpful resource for students doing undergraduate research projects using frames. The early chapters contain the topics from linear algebra that students need to know in order to read the rest of the book. The later chapters are devoted to advanced topics, which allow students with more experience to study more intricate types of frames. Toward that end, a Student Presentation section gives detailed proofs of fairly technical results with the intention that a student could work out these proofs independently and prepare a presentation to a class or research group. The authors have also presented some stories in the Anecdotes section about how this material has moti...

    Full Text Available Este estudo tem por objetivo investigar a relação existente entre a desnutrição energético-protéica e a cárie dentária precoce na primeira infância. Trata-se de uma comunicação, para a qual foi realizada uma revisão da literatura, a partir de análise documental de produção bibliográfica, baseada em levantamentos de periódicos e consultas a livros. Verificou-se que a cárie precoce na infância é altamente prevalente nas comunidades de baixa renda, nas quais a desnutrição é um fator comum e de grande relevância. Estudos mostram que crianças desnutridas tendem a apresentar defeitos estruturais no esmalte do dente, como também estão predispostas a um maior risco à cárie dentária. Portanto, uma deficiência energético-protéica durante a fase de desenvolvimento dentário (odontogênese tem demonstrado uma maior suscetibilidade à cárie dentária, atraso na cronologia de erupção e defeitos estruturais do esmalte (hipoplasia de esmalte, hipofunção das glândulas salivares e mudança na composição da saliva. Estes fatores podem ser os mecanismos pelos quais a desnutrição associa-se à cárie. Em conclusão, os estudos sugerem que a deficiência energético-protéica durante a odontogênese gera atraso na cronologia de erupção e defeitos estruturais no esmalte (hipoplasia, além de poder afetar as glândulas salivares, aumentando o risco de ocorrência da doença cárie. Estudos investigando associações entre desnutrição e cárie na primeira infância são de grande relevância para ampliar o conhecimento desta doença e o desenvolvimento de ações de promoção e de prevenção desse problema de saúde pública com aplicações nas áreas de nutrição e odontologia.This study aimed to investigate the relationship between protein-energy malnutrition and early childhood caries.

    The undergraduate curriculum in psychology profoundly reflects and shapes the discipline. Yet, reliable information on the undergraduate psychology curriculum has been difficult to acquire due to insufficient research carried out on unrepresentative program samples with disparate methods. In 2014, APA launched the first systematic effort in a decade to gather national data on the psychology major and program outcomes. We surveyed a stratified random sample of department chairs/coordinators of accredited colleges and universities in the United States that offer undergraduate courses and programs in psychology. A total of 439 undergraduate psychology programs (45.2%) completed the survey. This article summarizes, for both associate and baccalaureate programs, the results of the Undergraduate Study in Psychology. Current practices concerning the introductory course, the courses offered, core requirements, the psychology minor, and tracks/concentrations are presented. The frequency of formal program reviews and program-level assessment methods are also addressed. By extending prior research on the undergraduate curriculum, we chronicle longitudinal changes in the psychology major over the past 20 years. (c) 2016 APA, all rights reserved).

SÍNTESE DOS DADOS: Os dentes natais e neonatais consistem em uma anomalia de erupção, sendo caracterizados por seu irrompimento na cavidade oral durante o período intra-uterino ou no primeiro mês de vida respectivamente, podendo fazer parte da dentição decídua normal ou supranumerária. Esses dentes, em geral, apresentam bordos cortantes e podem estar relacionados ao aparecimento de ulcerações na base da língua do bebê e/ou no seio materno, comprometendo a amamentação. A fraca implantação óssea desses dentes favorece sua grande mobilidade, tornando-se, assim, um fator de risco à sua aspiração ou deglutição pela criança. A abordagem terapêutica depende da dentição à qual pertence o dente e dos possíveis problemas que este pode causar à saúde da criança ou da mãe. CONCLUSÕES: O conhecimento sobre as características clínicas e os possíveis distúrbios aos quais os dentes natais e neonatais estão relacionados por odontopediatras e pediatras possibilita a interação necessária para o diagnóstico precoce e a abordagem integral da criança.OBJECTIVE: To review available data about natal and neonatal teeth, emphasizing clinical characteristics, etiological factors, treatment, and the importance of the knowledge about this anomaly by pediatric dentists and pediatricians.

    Programs launched by many universities and the federal government expose many undergraduate students in the physical sciences to research early in their careers. However, in their research experiences, undergraduates are not usually introduced to the modes by which scientific knowledge, which they may have helped gather, is communicated and evaluated by working scientists. Nor is it always made clear where the research frontiers really lie. To this end, we guided a selected group of undergraduates through a national scientific conference, followed by a week of tutorials and discussions to help them better understand what had transpired. The program complemented the basic undergraduate research endeavors by emphasizing the importance of disseminating results both to other scientists and to society in general. Tutors and discussion leaders in the second week were experts in their fields and included some of the invited speakers from the main meeting. A considerable improvement in the understanding of the issues and prospects for a career in physics was discernible among the students after their two-week experience. copyright 1999 American Association of Physics Teachers

    Résumé Objectif Résumer les meilleures données portant sur les stratégies d’identification et de prise en charge des femmes qui présentent des antécédents familiaux de cancer du sein. Sources d’information Une recherche a été effectuée sur PubMed à l’aide des mots-clés anglais suivants : breast cancer, guidelines, risk, family history, management et magnetic resonance imaging screening, entre 2000 et 2016. La plupart des données sont de niveau II. Message principal Une bonne anamnèse familiale est essentielle lors de l’évaluation du risque de cancer du sein afin d’identifier les femmes qui sont candidates à une recommandation en counseling génétique pour un éventuel test génétique. On peut sauver des vies en offrant aux femmes porteuses d’une mutation au gène BRCA des interventions chirurgicales de réduction des risques (mastectomie bilatérale prophylactique, salpingo-ovariectomie bilatérale). Il faut encourager toutes les femmes qui présentent des antécédents familiaux de cancer du sein à demeurer actives et à limiter leur consommation d’alcool à moins de 1 verre par jour; certaines femmes sont admissibles à la chimioprévention. Il faut offrir aux femmes dont le risque à vie de cancer du sein est de 20 à 25 % ou plus un dépistage poussé par imagerie par résonance magnétique en plus d’une mammographie. Conclusion Une vie saine et la chimioprévention (chez les candidates) pourraient réduire l’incidence du cancer du sein; le dépistage poussé pourrait entraîner une détection plus précoce. Le fait d’aiguiller des femmes porteuses d’une mutation au BRCA vers la chirurgie de réduction des risques sauve des vies. PMID:27737991

    Full Text Available Uma das principais características da metodologia científica está na descrição detalhada de todas as condições experimentais e especialmente dos critérios adotados para se constituir uma amostra e obterem-se os dados. Esta característica deve ser aplicada em todos os trabalhos para permitir a outros estudiosos repetir o mesmo trabalho sob as mesmas condições descritas, e assim obter-se os mesmos resultados em qualquer parte do mundo. Esta possibilidade, além de permitir a checagem dos dados relatados, confere uma maior credibilidade perante a comunidade científica. Em ciência os dados devem ser públicos e reprodutíveis. Ao estudar-se as reabsorções dentárias, a padronização da amostra, dos critérios de diagnóstico e de classificação é muito importante. A reabsorção dentária representa um fenômeno multifatorial, ou seja, pode ser induzida por muitas causas e influenciadas por inúmeros fatores como morfologia dentária e óssea, proporção coroa-raiz, tipo de má oclusão, técnica empregada, extensão do movimento e outros. Para um trabalho sobre este tema apresentar maior credibilidade em seus resultados requer-se uma amostra muito homogênea, uma padronização do diagnóstico e da técnica ortodôntica com alto nível de calibração. Infelizmente muitos trabalhos sobre reabsorções dentárias, especialmente as que ocorrem durante o tratamento ortodôntico, são estudadas em amostras acumuladas no tempo, sem padronização diagnóstica e técnica, com pacientes tratados por inúmeros operadores, sem considerar a necessidade de padronização da amostra em algumas variáveis importantes nem tampouco relevá-las ou discuti-las quando das análises dos resultados.

    Brevik, Eric C.; Senturklu, Songul; Landblom, Douglas

    2015-04-01

    Several studies have demonstrated that undergraduate students benefit from research experiences. Benefits of undergraduate research include 1) personal and intellectual development, 2) more and closer contact with faculty, 3) the use of active learning techniques, 4) creation of high expectations, 5) development of creative and problem-solving skills, 6) greater independence and intrinsic motivation to learn, and 7) exposure to practical skills. The scientific discipline also benefits, as studies have shown that undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program (Lopatto, 2007). Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline. Soils form in the field, therefore, field experiences are very important in developing a complete and holistic understanding of soil science. Combining undergraduate research with field experiences can provide extremely beneficial outcomes to the undergraduate student, including increased understanding of and appreciation for detailed descriptions and data analysis as well as an enhanced ability to see how various parts of their undergraduate education come together to understand a complex problem. The experiences of the authors in working with undergraduate students on field-based research projects will be discussed, along with examples of some of the undergraduate research projects that have been undertaken. In addition, student impressions of their research experiences will be presented. Reference Lopatto, D. 2007. Undergraduate research experiences support science career decisions and active learning.

    There is little argument about the merits of undergraduate research, but it can seem like a complex, resource-intensive endeavor [e.g., Laursen et al., 2010; Lopatto, 2009; Hunter et al., 2006]. Although mentored undergraduate research can be challenging, the authors of this feature have found that research programs are strengthened when students and faculty collaborate to build new knowledge. Faculty members in the geology department at The College of Wooster have conducted mentored undergraduate research with their students for more than 60 years and have developed a highly effective program that enhances the teaching, scholarship, and research of our faculty and provides life-changing experiences for our students. Other colleges and universities have also implemented successful mentored undergraduate research programs in the geosciences. For instance, the 18 Keck Geology Consortium schools (http://keckgeology.org/), Princeton University, and other institutions have been recognized for their senior capstone experiences by U.S. News & World Report.

    2018-01-01

    The purpose of this 2-arm parallel trial was to assess the effect of the AcceleDent Aura appliance (OrthoAccel Technologies, Houston, Tex) on the rate of maxillary premolar extraction space closure in adolescent patients. Forty Class II adolescents treated with full fixed appliances and maxillary premolar extractions participated in this randomized clinical trial. They were recruited in a private practice and treated by 1 clinician. Randomization was accomplished in blocks of 10 patients assigned to either a no-appliance group or the AcceleDent Aura appliance group with the allocations concealed in opaque, sealed envelopes. Both the operator and the outcome assessor were blinded; however, it was not feasible to blind the patients. Models were taken of the maxillary arch at the start of space closure and just before complete space closure. The space was measured parallel to the occlusal plane from the cusp tips of the teeth mesial and distal to the extraction spaces. There was no clinically (0.05 mm per month; 95% confidence interval [CI], -0.24, 0.34) or statistically significant difference in the rate of space closure (P = 0.74). In both the univariable and multivariable analyses, the mean rate of tooth movement was slower by 0.13 mm per month (95% CI, -.26, .005) on the left side compared with the right side, but this was not statistically significant (P = 0.06). The AcceleDent Aura appliance had no effect on the rate of maxillary premolar extraction space closure. Only a few participants were considered to be good compliers with the appliance. However, the rate of space closure in the good compliers was similar to the overall group and did not appear to influence the result. This trial was not registered. The protocol was not published before trial commencement. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

  3. Cognitive diversity in undergraduate engineering: Dyslexia

    Science.gov (United States)

    Fitzpatrick, Velvet R.

    In the United States, institutions have established multiple programs and initiatives aimed at increasing the diversity of both faculty and students in engineering as means to produce a workforce that will better serve society. However, there are two major problems in addressing engineering student diversity. First, the engineering education research community has paid little attention to date as to how engineering education research characterizes diversity in its broadest sense. Second, research on persons with disabilities in undergraduates engineering, a population of interests within diversity, is minimal. Available disability studies tend to be skewed toward physical disabilities, leading to a neglect of cognitive differences such as learning disabilities (LD). In addition, disability research questions and study designs are inherently steeped in ability bias. The purpose of this dissertation is to explore the meaning of ability for students with dyslexia while in undergraduate engineering and establish the significance of cognitive diversity, focusing on LD and more specifically dyslexia, in undergraduate engineering education and answer the following research question: How do undergraduate engineering students with dyslexia experience ability while pursuing and persisting in engineering? The motivation was to lay the groundwork for future engineering education studies on undergraduate students with LD in general but dyslexia in specific. The first goal was to conduct a critical literature review pertaining to the academic strengths of undergraduate students with LD, specifically, dyslexia and the second goal was to describe how undergraduate engineering students with dyslexia experience ability. The intent was not to redefine dyslexia or disability. The intent is to provide an inclusive account of dyslexia, weakness and strengths, within the field of engineering education. This study was conducted from a qualitative inquiry approach, within the social

    Full Text Available Duzentos e oitenta leitões, entre 40 e 70 dias de idade, afetados pela sindrome multissistêmica do definhamento (SMD foram examinados após eutanásia para pesquisa de lesões dentárias. Pelo menos um abscesso periapical foi observado em 58 leitões (20,7%, dos quais 12 apresentaram abscessos múltiplos. Terceiros incisivos superiores, 3os incisivos inferiores, caninos superiores, caninos inferiores e outros dentes apresentaram respectivamente 22 (31,4%, 16 (22,9%, 4 (5,7%, 23 (32,9% e 5 (7,1% abscessos periapicais. A maior prevalência de abscessos observada nos dentes 3os incisivos e caninos inferiores está provavelmente associada com a maior área de corte ou desgaste que sofrem esses dentes. Entre as bactérias isoladas de amostras de 65 abscessos, Streptococcus sp. foi a mais prevalente e esteve presente em 21,48% e 27,7% dos isolados em aerobiose e anaerobiose, respectivamente. Na segunda posição em prevalência estiveram as bactérias corineformes, as quais foram mais freqüentemente isoladas em atmosfera anaeróbica do que aeróbica. Houve preponderância de isolamentos de bactérias Gram-positivas. Não foi possível determinar se as co-infecções bacterianas predispuseram às lesões características de SMD ou foram conseqüentes à imunossupressão causada pela infecção com PCV2.Swine producers have historically resected needle teeth of newborn pigs to prevent potential injuries to the sow mammary gland and faces of littermates. However, the possible impact of this practice on pig performance has been questioned. As part of a study, 280 PMWS affected piglets, with 40-70 days of age, were examined for the presence of dental lesions immediately after euthanasia. Most pigs were confirmed as PMWS by the detection of typical microscopic lesions and immunohistochemical pattern. At least one periapical abscess was observed in 58 piglets (20.7%, of which 12 had multiple abscesses. There were 22 (31.4%, 16 (22.9%, 4 (5.7%, 23 (32

    Matrix groups touch an enormous spectrum of the mathematical arena. This textbook brings them into the undergraduate curriculum. It makes an excellent one-semester course for students familiar with linear and abstract algebra and prepares them for a graduate course on Lie groups. Matrix Groups for Undergraduates is concrete and example-driven, with geometric motivation and rigorous proofs. The story begins and ends with the rotations of a globe. In between, the author combines rigor and intuition to describe basic objects of Lie theory: Lie algebras, matrix exponentiation, Lie brackets, and maximal tori.

    Full Text Available INTRODUÇÃO: A cárie dentária é a doença de maior prevalência da cavidade bucal gerando graves conseqüências econômicas e sociais. Estudos de prevalência de cárie dentária devem ser realizados periodicamente para o adequado planejamento das ações e serviços de saúde bucal. Assim, objetivou-se realizar estudo para conhecer a prevalência da cárie dentária em municípios do Estado de São Paulo, Brasil, medida através do índice CPO-D, na idade-índice de 12 anos, no período 1990-1995. MATERIAL E MÉTODO: Foram utilizados dados produzidos originalmente por secretarias ou departamentos municipais de saúde, obtidos através de instrumento concebido para essa finalidade, encaminhado aos 625 municípios do Estado de São Paulo, agrupados segundo o seu tipo e a região geográfica a que pertencem. RESULTADOS: Do total de 625 municípios, 237 (37,9% atenderam à solicitação de informações e 125 (20,0% dispunham de dados sobre o CPO-D, correspondendo a cerca de 5 mil crianças de 12 anos examinadas. O estudo revelou que em apenas 4,0% dos municípios a prevalência de cárie dentária é baixa, sendo alta ou muito alta em cerca de 80,0%. A variação nos valores do índice CPO-D ficou entre 1,3 e 13,6 e a média estimada para o Estado de São Paulo foi 4,8. Constatou-se ainda que os "grandes" municípios registraram 54,6% das suas populações enquadrando-se nas categorias de baixa ou moderada prevalência de cárie enquanto nos "pequenos" municípios 87,8% da população correspondiam às faixas de alta ou muito alta prevalência de cárie. CONCLUSÕES: A pesquisa evidenciou que os serviços municipais de saúde bucal, no estado de São Paulo, pouco tem se utilizado dos recursos básicos que a epidemiologia pode oferecer, indicando a necessidade de uma adequada formação de profissionais de saúde bucal na área de epidemiologia, em especial aqueles que exercem atividades de coordenação de serviços.

    Full Text Available Apesar da alta prevalência de oclusopatias em adolescentes ser mundialmente relatada, poucos estudos investigaram a associação entre oclusopatias definidas por critérios clínicos e a auto-avaliação da aparência dentária e das gengivas em adolescentes. O objetivo deste estudo foi investigar a associação entre oclusopatias e auto-avaliação da aparência dentária e gengival em adolescentes brasileiros. Foram utilizados os dados de um estudo transversal realizado com adolescentes de 15 a 19 anos de idade (n = 16.126 de 250 cidades localizadas nas cinco macrorregiões do Brasil. O desfecho foi a insatisfação com a aparência dentária e gengival, sendo a principal variável exploratória as oclusopatias, medidas através do Índice de Estética Dental - DAI. As demais variáveis exploratórias, potenciais fatores de confusão e mediação, foram renda familiar per capita, atraso escolar, condição de estudo, sexo, idade, cor da pele, agravos bucais (cárie não tratada, perda dentária devido à cárie, cálculo, fluorose e dor nos dentes e gengivas e a utilização dos serviços odontológicos. Realizaram-se análises de regressão de Poisson simples e multiva-riável. A prevalência de insatisfação com a aparência dos dentes e gengivas foi de 11,4% (IC 95%: 10,4-12,5. Todos os graus de oclusopatias foram associados à insatisfação com a aparência dos dentes e gengivas. A análise multivariável ajustada mostrou que a auto-avaliação negativa da aparência em adolescentes com oclusopatias graves ou muito graves foi 40% e 80% maior quando comparados àqueles com oclusão normal, respectivamente. Os resultados contribuem para a inclusão do critério de auto-avaliação da aparência dental durante as decisões de tratamento ortodôntico, principalmente no âmbito do Sistema Único de Saúde.In spite of the high prevalence of malocclusion in adolescents reported worldwide, there are few studies that have investigated the

    2010-06-01

    Humanities form an integral part of undergraduate medical curricula at numerous medical schools all over the world, and medical journals publish a considerable quantity of articles in this field. The aim of this study was to determine the extent to which the literature on humanities in undergraduate medical education seeks to provide evidence of a long-term impact of this integration of humanities in undergraduate medical education. Medline was searched for publications concerning the humanities in undergraduate medical education appearing from January 2000 to December 2008. All articles were manually sorted by the authors. Two hundred forty-five articles were included in the study. Following a qualitative analysis, the references included were categorized as "pleading the case," "course descriptions and evaluations," "seeking evidence of long-term impact," or "holding the horses." Two hundred twenty-four articles out of 245 either praised the (potential) effects of humanities on medical education or described existing or planned courses without offering substantial evidence of any long-term impact of these curricular activities on medical proficiency. Only 9 articles provided evidence of attempts to document long-term impacts using diverse test tools, and 10 articles presented relatively reserved attitudes toward humanities in undergraduate medical education. Evidence on the positive long-term impacts of integrating humanities into undergraduate medical education is sparse. This may pose a threat to the continued development of humanities-related activities in undergraduate medical education in the context of current demands for evidence to demonstrate educational effectiveness.

  16. Probe for detection of denting in PWR steam generator tubes

    International Nuclear Information System (INIS)

    1994-07-01

    In certain types of PWR steam generator, oxide deposits can lead to embedding, and subsequently to deformation of a tube (the phenomenon of ''denting''). Such embedding changes the vibratory behavior of the tubes and can result in fatigue cracking. This type of cracking can also be worsened in the event of improper assembly of the anti-vibration spacer bars supporting the U-bends. To prevent such incidents and provide for effective preventive condition-directed maintenance of its PWR steam generators, EDF has undertaken the study and development of a probe to detect this type of phenomenon. The studies began in 1990 and led to the building of an initial prototype probe. The principle behind the probe consists in inducing vibration in the U-bend and determining the main resonance modes of the tube. Measurements of frequency and amplitude and calculation of damping enable characterization of the mechanical behavior of the U-bend. The most important parameter is damping, for which the value must be sufficiently high to ensure that the tube is not subjected to major vibratory amplitudes during operation. Numerous tests have been performed with the first prototype version of the probe, on a mock-up in the test area and on one of the demounted steam generators on the Dampierre site. These different tests have enabled validation of the operating principle, fine-tuning the process, pinpointing certain mechanical problems in the probe design, and obtaining the first indications as to the real vibratory behavior of U-bends on a steam generator. On the basis of these preliminary tests, the specifications were drawn up for an industrial version of the probe. Following a call for bids and the choice of a manufacturer, work began on fabrication of a new probe model in 1993. This version was delivered at the end of 1993 and testing began in 1994.

    Undergraduate research (UR) is one of the most authentic and effective ways to promote student learning, and is a high-impact educational practice that can lead to measurable gains in student retention and graduation rates, as well as career aspirations. In recent years, UR has expanded from intensive summer one-on-one faculty-student mentored experiences to application in a variety of educational settings, including large lower division courses. The Council on Undergraduate Research (CUR), founded in 1978, is a national organization of individual (8000) and institutional members (650) within a divisional structure that includes geosciences, as well as 10 other thematic areas. CUR's main mission is to support and promote high-quality undergraduate student-faculty collaborative research and scholarship that develops learning through research. CUR fulfills this mission through extensive publication offerings, faculty and student-directed professional development events, and outreach and advocacy activities that share successful models and strategies for establishing, institutionalizing, and sustaining undergraduate research programs. Over the last decade, CUR has worked with hundreds of academic institutions, including two-year colleges, to develop practices to build undergraduate research into campus cultures and operations. As documented in CUR publications such as Characteristics of Excellence in Undergraduate Research (COEUR), strategies institutions may adopt to enhance and sustain UR often include: (1) the establishment of a central UR campus office, (2) extensive student and faculty participation in campus-based, as well as regional UR celebration events, (3) development of a consistent practice of assessment of UR's impact on student success, and, (4) establishment of clear policies for recognizing and rewarding faculty engagement in UR, particularly with respect to mentorship and publication with student scholars.

    Multidisciplinary undergraduate climate change education is critical for students entering any sector of the workforce. The University of Delaware has developed a new interdisciplinary affinity program—UD Climate Program for Undergraduates (CPUG)—open to undergraduate students of all majors to provide a comprehensive educational experience designed to educate skilled climate change problem-solvers for a wide range of professional careers. The program is designed to fulfill all General Education requirements, and includes a residential community commitment and experiential learning in community outreach and problem solving. Seminars will introduce current popular press and research materials and provide practice in confirming source credibility, communications training, and psychological support, as well as team building. As undergraduates, members of the UD CPUG team will define, describe, and develop a solution or solutions for a pressing local climate challenge that has the potential for global impact. The choice of a challenge and approach to addressing it will be guided by the student's advisor. Students are expected to develop a practical, multidisciplinary solution to address the challenge as defined, using their educational and experiential training. Solutions will be presented to the UD community during the spring semester of their senior year, as a collaborative team solution, with enhancement through individual portfolios from each team member. The logic model, structure, curricular and co-curricular supports for the CPUG will be provided. Mechanisms of support available through University administration will also be discussed.

    Full Text Available The aim of this study was to evaluate retrospectively the periodontal conditions of teeth with fixed crowns that had been in place from 3 to 5 years before the study was conducted. Forty individuals were recalled for a follow-up visit. Full-mouth clinical examinations were carried out and Visible Plaque Index (VPI, Gingival Bleeding Index (GBI, Probing Pocket Depth (PPD, and clinical attachment level (CAL were assessed in 6 sites per tooth. Parallel radiographs were also taken and blindly analyzed by a digital caliper (distance between the apex and the bone crest. BANA tests were performed. A contra-lateral sound tooth was considered the control. Mean values were obtained and Wilcoxon and paired sample t tests were used to compare the test and control sites. Crowns had a mean VPI value of 30.42% as compared to 49.17% for sound teeth. The GBI was 33.33% and 26.25% for test and control teeth respectively. Assessment of PPD revealed values of 2.30 and 2.14 mm, and assessment of CAL revealed averages of 2.02 and 1.89 mm for test and control teeth respectively. The mean values for radiographic distances were 12.73 and 13.67 mm, and for the BANA test, 67.50 and 50.00 for sound and crowned teeth, respectively. Statistically significant differences were observed for all parameters except for CAL and for the BANA test. It may be concluded that, with the methods used in the present study, crowns may be associated with more signs of inflammation, however not with periodontal breakdown.O objetivo deste estudo foi avaliar retrospectivamente as condições periodontais de pacientes com coroas fixas colocadas de 3 a 5 anos antes da realização da pesquisa.

Além disso, o programa apresenta a localização da discrepância por segmento - total, anterior e posterior - e individual - por elemento dentário, permitindo assim maior precisão na planificação das estratégias para a resolução dos problemas, caminhando para um tratamento ortodôntico de sucesso.The diagnosis of the Bolton’s Tooth Size Discrepancy is of fundamental importance for the good orthodontics finalization. Through the measurement of the teeth with the aid of a digital caliper and the insert of the values in the computer program developed by the authors and which that it will be presented in this article, the orthodontist’s work is simpler, because it is not necessary to accomplish any mathematical calculation or to aid of any table of values, eliminating the probability of mistakes. Besides, the program presents the location of the discrepancy for segment - overall, anterior and posterior - and individual - for dental element, allowing larger precision in the planning of the strategies for the resolution of the problems and walking for a success orthodontic treatment.

    The NSF-sponsored Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team (UAT) is a consortium of 19 institutions founded to promote undergraduate research and faculty development within the extragalactic ALFALFA HI blind survey project and follow-up programs. The collaborative nature of the UAT allows faculty and students from a wide ​range of public and private colleges and especially those with small astronomy programs to develop scholarly collaborations. Components of the program include an annual undergraduate workshop at Arecibo Observatory, observing runs at Arecibo, computer infrastructure, summer and academic year research projects, and dissemination at national meetings (e.g., Alfvin et al., Martens et al., Sanders et al., this meeting). Through this model, faculty and students are learning how science is accomplished in a large collaboration while contributing to the scientific goals of a major legacy survey. In the 7 years of the program, 23 faculty and more than 220 undergraduate students have participated at a significant level. 40% of them have been women and members of underrepresented groups. Faculty, many of whom were new to the collaboration and had expertise in other fields, contribute their diverse sets of skills to ALFALFA ​related projects via observing, data reduction, collaborative research, and research with students. 142 undergraduate students have attended the annual workshops at Arecibo Observatory, interacting with faculty, graduate students, their peers, and Arecibo staff in lectures, group activities, tours, and observing runs. Team faculty have supervised 131 summer research projects and 94 academic year (e.g., senior thesis) projects. 62 students have traveled to Arecibo Observatory for observing runs and 46 have presented their results at national meetings. 93% of alumni are attending graduate school and/or pursuing a career in STEM. Half of those pursuing graduate degrees in Physics or Astronomy are women. This work has been

    Undergraduate education is undergoing a shift away from the traditional transmission of a fixed body of knowledge to a learning approach where the emphasis is on supporting learners to learn. Central to this change is recognition that undergraduate education programmes should aim to develop independent learners who become effective lifelong learning practitioners. Successful independent learning as an undergraduate student or as a lifelong learner requires the learner to have well developed information literacy skills. An Online Electronic Information Skills (OEIS) intervention was designed to develop the information literacy skills in a cohort of second year undergraduate radiography students. An evaluation focused on learning outcomes was used to provide evidence of development of information literacy within the undergraduate course. The evaluation clearly demonstrated substantial skill development in students' ability to access scholarly information in their discipline area. The reported continued use of database searching by this cohort of students seven months after the OEIS intervention provides evidence that they are continuing to access and use scholarly information, information literacy skills necessary for their future work context.

    Full Text Available Thelma Quince, Pia Thiemann, John Benson, Sarah Hyde Primary Care Unit, Department of Public Health and Primary Care, Institute of Public Health, University of Cambridge, Cambridge, UK Abstract: Empathy is important to patient care. It enhances patients’ satisfaction, comfort, self-efficacy, and trust which in turn may facilitate better diagnosis, shared decision making, and therapy adherence. Empathetic doctors experience greater job satisfaction and psychological well-being. Understanding the development of empathy of tomorrow's health care professionals is important. However, clinical empathy is poorly defined and difficult to measure, while ways to enhance it remain unclear. This review examines empathy among undergraduate medical students, focusing upon three main questions: How is empathy measured? This section discusses the problems of assessing empathy and outlines the utility of the Jefferson Scale of Empathy – Student Version and Davis's Interpersonal Reactivity Index. Both have been used widely to assess medical students' empathy. Does empathy change during undergraduate medical education? The trajectory of empathy during undergraduate medical education has been and continues to be debated. Potential reasons for contrasting results of studies are outlined. What factors may influence the development of empathy? Although the influence of sex is widely recognized, the impact of culture, psychological well-being, and aspects of undergraduate curricula are less well understood. This review identifies three interrelated issues for future research into undergraduate medical students' empathy. First, the need for greater clarity of definition, recognizing that empathy is multidimensional. Second, the need to develop meaningful ways of measuring empathy which include its component dimensions and which are relevant to patients' experiences. Medical education research has generally relied upon single, self-report instruments, which have

As crianças foram sentadas em cadeiras escolares na sala da própria creche/escola para a execução do exame clínico; os menores de dois anos foram atendidos no sistema perna-perna ou joelho-joelho, por meio de iluminação natural e artificial. A protrusão dentária foi considerada quando sobressaliência maior que 3 mm, mensurada por meio de sonda periodontal milimetrada. A mordida aberta anterior foi registrada quando não houve contato com os dentes anteriores e os posteriores se mantiveram em oclusão. Foi registrada em ficha clínica a combinação dos dois tipos de maloclusão, ou seja, de mordida aberta e de protrusão dentária. Os dados foram avaliados estatisticamente pelo teste Qui-quadrado e a medida para avaliar a associação entre os eventos foi o odds ratio. A prevalência de protrusão dentária foi 66,1% e mordida aberta anterior, 19,8%; houve associação entre as maloclusões, idade e tipo de escola, porém não houve associação estatisticamente significante entre maloclusão e gênero.

    To compare learning styles of undergraduate and postgraduate medical students. Observational, comparative study. Department of Medical Education, Army Medical College, NUST, Rawalpindi, Pakistan, during February and March 2012. A total of 170 students were divided into two equal groups of undergraduate students of Army Medical College, and postgraduate students of Armed Forces Post Graduate Medical Institute, Rawalpindi. Learning Style Questionnaire (LSQ) was used to assess and categorize the participants into Honey and Mumford classification of learning styles. The responses of each student ranging from 'very strong,' 'strong', 'moderate', and 'low' preference towards activist, theorist, reflector and pragmatist learning styles were compiled. The two groups were compared using SPSS version 17, using Fisher's exact test and the chi-square test. A p-value of $lt; 0.05 was considered significant. Preferences for all four learning styles were present in both groups. The results reveal an overall statistically significant difference in the 'very strong' preference in learning styles between the two study groups (p=0.002). Among the undergraduate students, 45% had a very strong preference for being an activist, whereas in postgraduate students, 38% had very strong preference for reflector, and 35% for theorist. This was statistically significant for activist, and reflector, and attained a p-value of learning style was pragmatist in both undergraduate and postgraduate students. Diversity of learning styles at undergraduate and postgraduate level of medical education calls for multiplicity of instructional and assessment modalities to match them. The learning styles amongst the undergraduate medical students are different from the postgraduates. The postgraduates commonly have the reflector learning style while the undergraduates are predominantly activists and theorists.

    In the field of health practices, there are different models of health education. The objective of this article was to identify undergraduates' concepts of health education. This descriptive exploratory study used a qualitative approach. It was developed in the Undergraduate Nursing Courses of the Federal University of Santa Maria and Federal University of Rio Grande do Sul, Brazil. Subjects were undergraduate students of the last semester before graduation. Data were collected using a semistructured interview, and submitted to thematic content analysis. The results suggest that the undergraduate nursing students' training as health educators is permeated by concepts that are a mixture of traditional and modern assumptions on health education.

    The effectiveness of strength training on unstable surfaces (STU) versus stable surfaces (STS) or a control condition (CON; i.e., no training or regular training only) for strength, power and balance performance across the lifespan has not yet been investigated in a systematic review and meta-analysis. The aims of this systematic review and meta-analysis were to determine the general effects of STU versus STS or CON on muscle strength, power and balance in healthy individuals across the lifespan and to investigate whether performance changes following STU are age specific. A computerized systematic literature search was performed in the electronic databases PubMed and Web of Science from January 1984 up to February 2015. Initially, 209 articles were identified for review. Only controlled trials were included if they investigated STU in healthy individuals and tested at least one measure of maximal strength, strength endurance, muscle power, or static/dynamic balance. In total, 22 studies met the inclusion criteria. The included studies were coded for the following criteria: age, sex, training status, training modality, exercise and test modality. Effect size measures included within-subject standardized mean differences (SMDw) and weighted between-subject standardized mean differences (SMDb). Heterogeneity between studies was assessed using I2 and χ2 statistics. The methodological quality of each study was assessed using the Physiotherapy Evidence Database (PEDro) Scale. Our search failed to identify studies that examined the effects of STU versus STS or CON in children and middle-aged adults. However, four studies were identified that investigated the effects of STU versus CON or STS in adolescents, 15 studies were identified in young adults and three studies were identified in old adults. Compared with CON, STU produced medium effects on maximal strength in young adults and no effects to medium effects in old adults. In addition, large effects were detected on

  6. Undergraduate Students’Evaluation Criteria When Using Web Resources for Class Papers

    2004-09-01

    Full Text Available The growth in popularity of the World Wide Web has dramatically changed the way undergraduate students conduct information searches. The purpose of this study is to investigate what core quality criteria undergraduate students use to evaluate Web resources for their class papers and to what extent they evaluate the Web resources. This study reports on five Web page evaluations and a questionnaire survey of thirty five undergraduate students in the Information Technology and Informatics Program at Rutgers University. Results show that undergraduate students have become increasingly sophisticated about using Web resources, but not yet sophisticated about searching them. Undergraduate students only used one or two surface quality criteria to evaluate Web resources. They made immediate judgments about the surface features of Web pages and ignored the content of the documents themselves. This research suggests that undergraduate instructors should take the responsibility for instructing students on basic Web use knowledge or work with librarians to develop undergraduate students information literacy skills.

Three mongrel dogs were used and ten class V cavities were prepared on their teeth. A mechanic pulp exposure was produced with a sterile exploratory probe in the central portion of each cavity and bleeding was controlled with dry sterile cotton pellets. Enamel, dentin and the site of the pulp exposure of five teeth were etched with 35% phosphoric acid followed by the application of an adhesive system (Scotchbond Multi-Purpose - 3M. In the other five teeth, calcium hydroxide cement (Hydro C - Dentsply was applied on the site of the pulp exposition before application of the adhesive system (Scotchbond Multi-Purpose - 3M. All teeth were restored with a resin composite (Z-100 - 3M. After 7, 30 or 45 days the dogs were anesthetized and perfused with saline followed by a solution of neutral buffered formalin. Maxilla and mandible were sectioned into three parts and placed in a solution for demineralization. Following bone demineralization, all teeth were cut, trimmed, embedded in paraffin and longitudinally cut. Then, the teeth were stained with hematoxilin and eosin and observed under a light microscope. The results obtained with the treatments proposed in this study showed the presence and persistence of an inflammatory response of different intensities at the three experimental periods. There was no variation in the inflammatory response regarding the different treatments performed.O objetivo deste estudo foi de avaliar a resposta pulpar de dentes decíduos de cães à um sistema adesivo ou a um cimento de hidróxido de cálcio após exposição mecânica da polpa.

    How can we best internationalize undergraduate psychology education in the United States and elsewhere? This question is more timely than ever, for at least 2 reasons: Within the United States, educators and students seek greater contact with psychology programs abroad, and outside the United States, psychology is growing apace, with educators and students in other nations often looking to U.S. curricula and practices as models. In this article, we outline international developments in undergraduate psychology education both in the United States and abroad, and analyze the dramatic rise of online courses and Internet-based technologies from an instructional and international point of view. Building on the recommendations of the 2005 APA Working Group on Internationalizing the Undergraduate Psychology Curriculum, we then advance 14 recommendations on internationalizing undergraduate psychology education--for students, faculty, and institutions.

    Full Text Available Los quistes dentígeros suelen ser, en la mayor parte de los casos, un hallazgo casual; por lo general se descubren al investigar la no erupción de un diente permanente. Ocupan el segundo lugar en frecuencia de aparición en los maxilares después del quiste radicular. Cuando el seno maxilar es invadido por estos quistes los síntomas usualmente aparecen tardíos en el proceso. Estos pueden incluir dolor facial, parestesia como consecuencia de la presión sobre un nervio, dolor de cabeza, trismo, trastornos de la gustación y congestión nasal. Por lo infrecuente de la localización maxilar y la corta edad de la paciente nos vimos motivados a revisar lo más reciente de la bibliografía que aborda este tema y a presentar el caso clínico de una paciente femenina de 17 años que fue diagnosticada y tratada por presentar un quiste dentígero en dicha ubicación. Se enfatiza en la importancia del correcto diagnóstico y el establecimiento de una terapéutica concordante en cada caso.Dentigerous cysts are a casual finding in most of cases, in general discovered in investigation of a not eruption of permanent tooth.

    2001-04-01

    Undergraduate physics programs in the United States are under stress because of changes in the scientific and educational environment in which they operate. The number of undergraduate physics majors is declining nationwide; there is some evidence that the "best" undergraduate students are choosing majors other than physics, and funding agencies seem to be emphasizing K-12 education. How can physics departments respond creatively and constructively to these changes? After describing some of the details of the current environment, I will discuss the activities of the National Task Force on Undergraduate Physics, supported by the American Institute of Physics, the America Physical Society, the American Association of Physics Teachers and the ExxonMobil Foundation. I will also present some analysis of Task Force site visits to departments that have thriving undergraduate physics programs, pointing out the key features that seem to be necessary for success. Among these features are department-wide recruitment and retention efforts that are the theme of this session.

    For more than seven years, the Council on Undergraduate Research (CUR), the primary organization supporting programs, services, and advocacy for undergraduate research, has been working with support from the NSF's Division of Undergraduate Education (DUE) to enhance, sustain, and institutionalize undergraduate research in diverse STEM disciplines and higher education settings. The Council on Undergraduate Research comprises more than 9000 individual and 670 institutional members within a divisional structure that includes geosciences, as well as 11 other thematic areas. Through its most recent grant: 'Transformational Learning through Undergraduate Research: Comprehensive Support for Faculty, Institutions, State Systems and Consortia' (NSF DUE CCLI III Award #09-20275), CUR has been collaborating with six higher education systems, each selected after a rigorous national application process in 2010 and 2011. These six systems, which collectively represent 79 individual institutions, are the Council of Public Liberal Arts Colleges (COPLAC), University of Wisconsin System (UWS), California State University System (CSU), City University of New York (CUNY), Great Lakes Colleges Association (GLCA), and Pennsylvania State System of Higher Education (PASSHE). The more than 350 participants of faculty and senior-level administrators from the six systems are engaged in shared multi-faceted and multi-year professional development experiences. Teams from each system attended customized institutes facilitated by CUR experts in 2011-2012, during which the teams developed specific action plans focused on institutionalizing undergraduate research on their campus and within their system. The systems were reconvened as a group a year after the first institute, to chart progress toward achieving their goals. Based on interviews and surveys with participants, campus teams are making substantial progress toward implementation of robust undergraduate research programs, and are making

    Empathy is important to patient care. It enhances patients’ satisfaction, comfort, self-efficacy, and trust which in turn may facilitate better diagnosis, shared decision making, and therapy adherence. Empathetic doctors experience greater job satisfaction and psychological well-being. Understanding the development of empathy of tomorrow’s health care professionals is important. However, clinical empathy is poorly defined and difficult to measure, while ways to enhance it remain unclear. This review examines empathy among undergraduate medical students, focusing upon three main questions: How is empathy measured? This section discusses the problems of assessing empathy and outlines the utility of the Jefferson Scale of Empathy – Student Version and Davis’s Interpersonal Reactivity Index. Both have been used widely to assess medical students’ empathy. Does empathy change during undergraduate medical education? The trajectory of empathy during undergraduate medical education has been and continues to be debated. Potential reasons for contrasting results of studies are outlined. What factors may influence the development of empathy? Although the influence of sex is widely recognized, the impact of culture, psychological well-being, and aspects of undergraduate curricula are less well understood. This review identifies three interrelated issues for future research into undergraduate medical students’ empathy. First, the need for greater clarity of definition, recognizing that empathy is multidimensional. Second, the need to develop meaningful ways of measuring empathy which include its component dimensions and which are relevant to patients’ experiences. Medical education research has generally relied upon single, self-report instruments, which have utility across large populations but are limited. Finally, there is a need for greater methodological rigor in investigating the possible determinants of clinical empathy in medical education. Greater

    Full Text Available OBJETIVO: A proposta do trabalho foi verificar a relação entre defeitos do esmalte e atraso da erupção dentária com prematuridade. MÉTODOS: A amostra consistiu de 100 crianças prematuras, entre seis meses a seis anos de idade em acompanhamento no Instituto da Criança da Faculdade de Medicina da USP. Foi feita uma anamnese da cavidade bucal por apenas um observador, avaliando o tempo da erupção dentária e a ocorrência de defeitos no esmalte. Realizou-se também uma avaliação médica, com dados referentes a possíveis problemas durante o período pré-natal, neonatal e pós-natal. A avaliação estatística utilizou análise descritiva, freqüência média e intervalo de confiança de 95%. RESULTADOS: Defeitos apareceram em 35% das crianças prematuras; 51,43% das que tinham defeitos haviam nascido com peso baixo (2500g . Não houve relação entre ocorrência de defeitos com baixo Boletim de Apgar em 1 minuto, 2 minutos e 5 minutos (p=0,628; p=0,308; p=0,193. Os defeitos mais comuns foram as opacidades brancas, tanto na dentição decídua (19% quanto na permanente (100%.

    2018-06-01

    The rapid growth in undergraduate public health education has offered training in epidemiology to an increasing number of undergraduate students. Epidemiology courses introduce undergraduate students to a population health perspective and provide opportunities for these students to build essential skills and competencies such as ethical reasoning, teamwork, comprehension of scientific methods, critical thinking, quantitative and information literacy, ability to analyze public health information, and effective writing and oral communication. Taking a varied approach and incorporating active learning and assessment strategies can help engage students in the material, improve comprehension of key concepts, and further develop key competencies. In this commentary, we present examples of how epidemiology may be taught in the undergraduate setting. Evaluation of these approaches and others would be a valuable next step.

    2015-04-01

    Several studies crossing numerous disciplinary boundaries have demonstrated that undergraduate students benefit from research experiences. These benefits include personal and intellectual development, more and closer contact with faculty, the use of active learning techniques, the creation of high expectations, the development of creative and problem-solving skills, and the development of greater independence and intrinsic motivation to learn. The discipline also gains in that studies show undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program. Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline, therefore enhancing their professional socialization into their chosen field. If the goals achieved by undergraduate research include introducing these students to the advancement of their chosen field, it stands to reason the ultimate ending to this experience would be the publication of a peer-reviewed paper. While not all undergraduate projects will end with a product worthy of peer-reviewed publication, some definitely do, and the personal experience of the authors indicates that undergraduate students who achieve publication get great satisfaction and a sense of personal achievement from that publication. While a top-tier international journal probably isn't going to be the ultimate destination for many of these projects, there are several appropriate outlets. The SSSA journal Soil Horizons has published several undergraduate projects in recent years, and good undergraduate projects can often be published in state academy of science journals. Journals focused expressly on publishing undergraduate research include the Journal of Undergraduate Research and Scholarly Excellence, Reinvention, and the American Journal of Undergraduate Research.

    Full Text Available Purpose: Studying and analyzing the undergraduate engineering students' leadership skills to discover their potential leadership strengths and weaknesses. This study will unveil potential ways to enhance the ways we teach engineering leadership. The research has great insights that might assist engineering programs to improve curricula for the purpose of better engineering preparation to meet industry's demands. Methodology and Findings: 441 undergraduate engineering students have been surveyed in two undergraduate engineering programs to discover their leadership skills. The results in both programs were revealing that undergraduate engineering students are lacking behind in the visionary leadership skills compared to directing, including and cultivating leadership styles. Recommendation: A practical framework has been proposed to enhance the lacking leadership skills by utilizing the Matrix of Change (MOC, and the Balanced Scorecard BSC to capture the best leadership scenarios to design virtual simulation environment as per the lacking leadership skills which is the visionary leadership skills in this case. After that, the virtual simulation will be used to provide an experiential learning by replacing human beings with avatars that can be managed or dramatized by real people to enable the creation of live, practical, measurable, and customizable leadership development programs.

  7. Burnout in premedical undergraduate students.

    Fang, Daniel Z; Fang, Daniel; Young, Christina B; Young, Christina; Golshan, Shah; Moutier, Christine; Zisook, Sidney

    2012-01-01

    There has been growing recognition that medical students, interns, residents and practicing physicians across many specialties are prone to burnout, with recent studies linking high rates of burnout to adverse mental health issues. Little is known about the trajectory and origins of burnout or whether its roots may be traced to earlier in medical training, specifically, during undergraduate studies. Here, the authors surveyed undergraduates at UC San Diego (UCSD) to assess the relationship of burnout to premedical status while controlling for depression severity. Undergraduate students at UCSD were invited to participate in a web-based survey, consisting of demographic questions; the Maslach Burnout Inventory Student Survey (MBI-SS), which gauged the three dimensions of burnout; and the nine-item Patient Health Questionnaire (PHQ-9), to assess depression severity. A total of 618 premedical students and 1,441 non-premedical students completed the questionnaire. Premedical students had greater depression severity and emotional exhaustion than non-premedical students, but they also exhibited a greater sense of personal efficacy. The burnout differences were persistent even after adjusting for depression. Also, premedical women and Hispanic students had especially high levels of burnout, although differences between groups became nonsignificant after accounting for depression. Despite the limitations of using a burnout questionnaire not specifically normed for undergraduates, the unique ethnic characteristics of the sample, and the uncertain response rate, the findings highlight the importance of recognizing the unique strains and mental health disturbances that may be more common among premedical students than non-premedical students. Results also underscore the close relationship between depression and burnout, and point the way for subsequent longitudinal, multi-institutional studies that could help identify opportunities for prevention and intervention.

    2018-02-01

    Pro-environmental behavior is an individual action as a manifestation of one's responsibility to create a sustainable environment. University students as one of the agent of change can adopt pro-environmental behaviors concept, even through simple things to do on daily activities such as ride a bicycle or walk for short distance, reuse the shopping bags, separate waste, learn about environmental issues etc. Many studies have examined pro-environmental behavior from various approaches. However, the study about university students' pro-environmental behavior is lacking. The aim of this paper is to examine the undergraduate students' pro-environmental behaviors level. We surveyed 364 first year undergraduate students from a state university in Semarang. The survey included six aspects of pro-environmental behavior in daily practice which include energy conservation, mobility and transportation, waste avoidance, recycling, consumerism, and vicarious behaviors toward conservation. Findings of this study showed the level of pro-environmental behavior of first year undergraduate students is medium. Recommendations for undergraduate students and future researchers are discussed.

    Full Text Available The purpose of this paper is to describe the new experiences of the dual training model in engineering education in Hungary. This new model has been introduced recently in the higher education and has become a focus of interest. This is a fa-vorable program for the students to experience the real industry environment pri-or to graduation and it is a good tool to motivate them to study harder. The dual education students study in the institutional academic period together with the regular full-time students at their higher education institute, and parallel to their academic education they participate in the practical training. It gives the students an opportunity to join a specific training program at an enterprise. Being involved in specific "operational" practical tasks and project-oriented work enhances inde-pendent work, learning soft skills and experiencing the culture of work. Our ob-jectives are to analyze the benefits of the dual training for all three parties: the stu-dent, the company and university. The study confirms earlier results from prior studies which show, for example, that students who choose the dual option achieve better program outcomes.

    Pedone, Maggie Helene

    The underrepresentation of women in science, technology, engineering, and mathematics (STEM) is a complex problem that continues to persist at the postsecondary level, particularly in computer science and engineering fields. This dissertation explored the pre-college and college level factors that influenced undergraduate women's persistence in STEM. This study also examined and compared the characteristics of undergraduate women who entered STEM fields and non-STEM fields in 2003-2004. The nationally representative Beginning Postsecondary Students Longitudinal Study (BPS:04/09) data set was used for analysis. BPS:04/09 study respondents were surveyed three times (NPSAS:04, BPS:04/06, BPS:04/09) over a six-year period, which enabled me to explore factors related to long-term persistence. Astin's Input-Environment-Output (I-E-O) model was used as the framework to examine student inputs and college environmental factors that predict female student persistence (output) in STEM. Chi-square tests revealed significant differences between undergraduate women who entered STEM and non-STEM fields in 2003-2004. Differences in student demographics, prior academic achievement, high school course-taking patterns, and student involvement in college such as participation in study groups and school clubs were found. Notably, inferential statistics showed that a significantly higher proportion of female minority students entered STEM fields than non-STEM fields. These findings challenge the myth that underrepresented female minorities are less inclined to enter STEM fields. Logistic regression analyses revealed thirteen significant predictors of persistence for undergraduate women in STEM. Findings showed that undergraduate women who were younger, more academically prepared, and academically and socially involved in college (e.g., lived on campus, interacted with faculty, participated in study groups, fine arts activities, and school sports) were more likely to persist in STEM

    Sa'adah, S.; Hidayat, T.; Sudargo, Fransisca

    2017-04-01

    The Phylogenetic tree is a visual representation depicts a hypothesis about the evolutionary relationship among taxa. Evolutionary experts use this representation to evaluate the evidence for evolution. The phylogenetic tree is currently growing for many disciplines in biology. Consequently, learning about the phylogenetic tree has become an important part of biological education and an interesting area of biology education research. Skill to understanding and reasoning of the phylogenetic tree, (called tree thinking) is an important skill for biology students. However, research showed many students have difficulty in interpreting, constructing, and comparing among the phylogenetic tree, as well as experiencing a misconception in the understanding of the phylogenetic tree. Students are often not taught how to reason about evolutionary relationship depicted in the diagram. Students are also not provided with information about the underlying theory and process of phylogenetic. This study aims to investigate the initial ability of undergraduate students in understanding and reasoning of the phylogenetic tree. The research method is the descriptive method. Students are given multiple choice questions and an essay that representative by tree thinking elements. Each correct answer made percentages. Each student is also given questionnaires. The results showed that the undergraduate students’ initial ability in understanding and reasoning phylogenetic tree is low. Many students are not able to answer questions about the phylogenetic tree. Only 19 % undergraduate student who answered correctly on indicator evaluate the evolutionary relationship among taxa, 25% undergraduate student who answered correctly on indicator applying concepts of the clade, 17% undergraduate student who answered correctly on indicator determines the character evolution, and only a few undergraduate student who can construct the phylogenetic tree.

    2013-11-01

    Discussions of and recommendations for the training of clinical neuropsychologists exist at the doctoral, internship, and post-doctoral level. With few exceptions, the literature on undergraduate preparations in clinical neuropsychology is sparse and lacks empirical evidence. In the present study, graduate-level faculty and current trainees completed surveys about graduate school preparations. Faculty expectations of minimum and ideal undergraduate training were highest for research methods, statistics, and assessment. Preferences for "goodness of fit" also emerged as important admissions factors. These results offer evidence for desirable undergraduate preparations for advanced study in clinical neuropsychology. Although undergraduate training in psychology is intentionally broad, results from this study suggest that students who desire advanced study in clinical neuropsychology need to tailor their experiences to be competitive in the application process. The findings have implications for prospective graduate students, faculty who train and mentor undergraduates, and faculty who serve on admissions committees.

    There is a dearth of mental health research on undergraduates in Sri Lanka. This study examines the prevalence of depression in a sample of Sri Lankan undergraduates, their exposure to threatening life events and the predictors of their depression. Responses of 4304 undergraduates were obtained on the Patient Health Questionnaire-9 and a measure of exposure to threatening life events, with binary logistic regression models used to identify the demographic and life event correlates of screening positive for Major Depressive Disorder (MDD). PHQ-9 diagnoses of 'Major' and 'Other' depression were obtained by 9.3% and 13.5% of undergraduates, respectively. A higher likelihood of MDD was seen among those who were older and those living in hostels (compared to home), although no differences were seen between genders or those studying in different faculties. Likelihood of MDD was higher in undergraduates exposed to multiple threatening life events as well as those exposed to physical threat; family deaths; romantic break-ups; a problem with a close associate; educational difficulties; unemployment and domestic violence, and among male undergraduates harassed by another student. MDD is prevalent in these undergraduates and universities need to develop services to assist them. Such services may also need to focus on supporting those who have experienced threatening life events, particularly those that arise as a result of being an undergraduate, as these may increase the risk of MDD.

  14. SPIN-UP and Preparing Undergraduate Physics Majors for Careers in Industry

    Science.gov (United States)

    Howes, Ruth

    2011-03-01

    Seven years ago, the Strategic Programs for Innovations in Undergraduate Physics (SPIN-UP) Report produced by the National Task Force on Undergraduate Physics identified several key characteristics of thriving undergraduate physics departments including steps these departments had taken to prepare students better for careers in industry. Today statistical data from AIP shows that almost 40% of students graduating with a degree in physics seek employment as soon as they graduate. Successful undergraduate physics programs have taken steps to adapt their rigorous physics programs to ensure that graduating seniors have the skills they need to enter the industrial workplace as well as to go on to graduate school in physics. Typical strategies noted during a series of SPIN-UP workshops funded by a grant from NSF to APS, AAPT, and AIP include flexible curricula, early introduction of undergraduates to research techniques, revised laboratory experiences that provide students with skills they need to move directly into jobs, and increased emphasis on ``soft'' skills such as communication and team work. Despite significant success, undergraduate programs face continuing challenges in preparing students to work in industry, most significantly the fact that there is no job called ``physicist'' at the undergraduate level. supported by grant NSF DUE-0741560.

    Psychiatric disorders are highly prevalent and remains a huge burden on the society. In spite of that persons with mental illness are marginalized and mental health is largely being neglected. There is an acute shortage of mental health professionals in India, and also there is inadequate exposure to psychiatry during the medical undergraduate training in India. Moreover, the perception towards psychiatry and psychiatrists is not favorable among medical fraternity and policy makers. This is reflected in the fact that in spite of clearly deficient undergraduate psychiatry curriculum, no steps have been taken towards improving it and recommendations are not being implemented in true spirit. This review tries to identify the gaps in undergraduate curriculum, present a SWOT analysis of current situation and recommend the possible ways to address the deficiencies particularly in India.

    Full Text Available Vulcanization property and structure-properties relationship of natural rubber (NR/silica (SiO2 composites modified by a novel multi-functional rubber agent, N-phenyl- N'-(γ-triethoxysilane-propyl thiourea (STU, are investigated in detail. Results from the infrared spectroscopy (IR and X-ray photoelectron spectroscopy (XPS show that STU can graft to the surface of SiO2 under heating, resulting in a fine-dispersed structure in the rubber matrix without the connectivity of SiO2 particles as revealed by transmission electron microscopy (TEM. This modification effect reduces the block vulcanization effect of SiO2 for NR/SiO2/STU compounds under vulcanization process evidently. The 400% modulus and tensile strength of NR/SiO2/STU composites are much higher than that of NR/SiO2/TU composites, although the crystal index at the stretching ratio of 4 and crosslinking densities of NR/SiO2 composites are almost the same at the same dosage of SiO2. Consequently, a structure-property relationship of NR/SiO2/STU composites is proposed that the silane chain of STU can entangle with NR molecular chains to form an interfacial region, which is in accordance with the experimental observations quite well.

    2015-01-01

    Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical "big data" opens the possibility of utilizing biocuration as a means to mine today's data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8-50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week.

    2012-12-01

    URSSA is the Undergraduate Research Student Self-Assessment, an online survey instrument for programs and departments to use in assessing the student outcomes of undergraduate research (UR). URSSA focuses on what students learn from their UR experience, rather than whether they liked it. The online questionnaire includes both multiple-choice and open-ended items that focus on students' gains from undergraduate research. These gains include skills, knowledge, deeper understanding of the intellectual and practical work of science, growth in confidence, changes in identity, and career preparation. Other items probe students' participation in important research-related activities that lead to these gains (e.g. giving presentations, having responsibility for a project). These activities, and the gains themselves, are based in research and thus constitute a core set of items. Using these items as a group helps to align a particular program assessment with research-demonstrated outcomes. Optional items may be used to probe particular features that are augment the research experience (e.g. field trips, career seminars, housing arrangements). The URSSA items are based on extensive, interview-based research and evaluation work on undergraduate research by our group and others. This grounding in research means that URSSA measures what we know to be important about the UR experience The items were tested with students, revised and re-tested. Data from a large pilot sample of over 500 students enabled statistical testing of the items' validity and reliability. Optional items about UR program elements were developed in consultation with UR program developers and leaders. The resulting instrument is flexible. Users begin with a set of core items, then customize their survey with optional items to probe students' experiences of specific program elements. The online instrument is free and easy to use, with numeric results available as raw data, summary statistics, cross-tabs, and

    2017-01-01

    Electrical impedance tomography (EIT) has undergone 30 years of development. Functional chest examinations with this technology are considered clinically relevant, especially for monitoring regional lung ventilation in mechanically ventilated patients and for regional pulmonary function testing in patients with chronic lung diseases. As EIT becomes an established medical technology, it requires consensus examination, nomenclature, data analysis and interpretation schemes. Such consensus is needed to compare, understand and reproduce study findings from and among different research groups, to enable large clinical trials and, ultimately, routine clinical use. Recommendations of how EIT findings can be applied to generate diagnoses and impact clinical decision-making and therapy planning are required. This consensus paper was prepared by an international working group, collaborating on the clinical promotion of EIT called TRanslational EIT developmeNt stuDy group. It addresses the stated needs by providing (1) a new classification of core processes involved in chest EIT examinations and data analysis, (2) focus on clinical applications with structured reviews and outlooks (separately for adult and neonatal/paediatric patients), (3) a structured framework to categorise and understand the relationships among analysis approaches and their clinical roles, (4) consensus, unified terminology with clinical user-friendly definitions and explanations, (5) a review of all major work in thoracic EIT and (6) recommendations for future development (193 pages of online supplements systematically linked with the chief sections of the main document). We expect this information to be useful for clinicians and researchers working with EIT, as well as for industry producers of this technology. Published by the BMJ Publishing Group Limited.

    Chhabra, Mahima; Das, Ritwick

    2017-01-01

    Quantum mechanics (QM) forms the most crucial ingredient of modern-era physical science curricula at undergraduate level. The abstract ideas involved in QM related concepts pose a challenge towards appropriate visualization as a consequence of their counter-intuitive nature and lack of experiment-assisted visualization tools. At the heart of the quantum mechanical formulation lies the concept of ‘wavefunction’, which forms the basis for understanding the behavior of physical systems. At undergraduate level, the concept of ‘wavefunction’ is introduced in an abstract framework using mathematical tools and therefore opens up an enormous scope for alternative conceptions and erroneous visualization. The present work is an attempt towards exploring the visualization models constructed by undergraduate students for appreciating the concept of ‘wavefunction’. We present a qualitative analysis of the data obtained from administering a questionnaire containing four visualization based questions on the topic of ‘wavefunction’ to a group of ten undergraduate-level students at an institute in India which excels in teaching and research of basic sciences. Based on the written responses, all ten students were interviewed in detail to unravel the exact areas of difficulty in visualization of ‘wavefunction’. The outcome of present study not only reveals the gray areas in students’ conceptualization, but also provides a plausible route to address the issues at the pedagogical level within the classroom.

  16. Alive and aware: Undergraduate research as a mechanism for program vitalization

    Science.gov (United States)

    Rohs, C.

    2013-12-01

    Undergraduate research is a vital component of many geoscience programs across the United States. It is especially critical at those institutions that do not have graduate students or graduate programs in the geosciences. This paper presents findings associated with undergraduate research in four specific areas: The success of students that pursue undergraduate research both in the workforce and in graduate studies; the connections that are generated through undergraduate research and publication; the application of undergraduate research data and materials in the classroom; and the development of lasting connections between faculty and students to construct a strong alumni base to support the corresponding programs. Students that complete undergraduate research have the opportunity to develop research proposals, construct budgets, become familiar with equipment or software, write and defend their results. This skill set translates directly to graduate studies; however, it is also extremely valuable for self-marketing when seeking employment as a geoscientist. When transitioning from higher education into the workforce, a network of professional connections facilitates and expedites the process. When completing undergraduate research, students have a direct link to the faculty member that they are working with, and potentially, the network of that faculty member. Even more important, the student begins to build their own professional network as they present their findings and receive feedback on their research. Another area that benefits from undergraduate research is the classroom. A cyclical model is developed where new data and information are brought into the classroom by the faculty member, current students see the impact of undergraduate research and have the desire to participate, and a few of those students elect to participate in a project of their own. It turns into a positive feedback loop that is beneficial for both the students and the faculty members

    Learning in general practice is an essential component of undergraduate medical education; currently, on average, 13% of clinical placements in the UK are in general practice. However, whether general practice can sustainably deliver more undergraduate placements is uncertain. To identify the geographical distribution of undergraduate teaching practices and their distance from the host medical school. National survey of all medical schools in the UK. All 33 UK medical schools were invited to provide the postcodes of their undergraduate teaching practices. These were collated, de-duplicated, and mapped. The distance in kilometres and journey times by car and public transport between each medical school and its teaching practices was estimated using Transport Direct (www.transportdirect.info). The postcodes of every practice in the UK were obtained from the UK's health departments. All 33 UK medical schools responded; 4392 practices contributed to teaching, with a median (minimum-maximum) of 142 (17-385) practices per school. The median (minimum-maximum) distance between a school and a teaching practice was 28 km (0-1421 km), 41 (0:00-23:26) minutes' travel by car and 1 hour 12 (0:00-17:29) minutes' travel by public transport. All teaching practices were accessible by public transport in one school and 90-99% were in a further four schools; 24 schools had >20% of practices that were inaccessible by public transport. The 4392 undergraduate teaching general practices are widely distributed and potentially any practice, no matter how isolated, could contribute to undergraduate education. However, this is, at the price of a considerable travel burden. © British Journal of General Practice 2014.

  6. Matrix groups for undergraduates

    2014-04-01

    Full Text Available The smartphones ownership among the undergraduates in Malaysia was recorded as high. However, little was known about its utilization patterns, thus, the focus of this research was to determine the utilisation patterns of smartphones based on the National Education Technology Standard for Students (NETS.S among engineering undergraduates in Malaysia. This study was based on a quantitative research and the population comprised undergraduates from four Malaysian Technical Universities. A total of 400 questionnaires were analyzed. Based on the results, the undergraduates’ utilisation level of smartphones for communication and collaboration tool was at a high level. Meanwhile, utilisation for operations and concepts tool and research and information fluency tool were at moderate level. Finally, smartphones utilisation as digital citizenship tool and critical thinking, problem solving and creativity tool were both at a low level. Hence, more training and workshops should be given to the students in order to encourage them to fully utilise smartphones in enhancing the higher order thinking skills.

    2017-06-01

    Life science professional societies play important roles for undergraduates in their fields and increasingly offer membership, fellowships, and awards for undergraduate students. However, the overall impacts of society-student interactions have not been well studied. Here, we sought to develop and test a pilot survey of undergraduate students to determine how they got involved in research and in presenting at the Experimental Biology (EB) meeting, what they gained from the scientific and career development sessions at the meeting, and how the American Physiological Society (APS) can best support and engage undergraduate students. This survey was administered in 2014 and 2015 to undergraduate students who submitted physiology abstracts for and attended EB. More than 150 students responded (38% response rate). Respondents were demographically representative of undergraduate students majoring in life sciences in the United States. Most students (72%) became involved in research through a summer research program or college course. They attended a variety of EB sessions, including poster sessions and symposia, and found them useful. Undergraduate students interacted with established researchers at multiple venues. Students recommended that APS provide more research fellowships (25%) and keep in touch with students via both e-mail (46%) and social media (37%). Our results indicate that APS' EB undergraduate activities are valued by students and are effective in helping them have a positive scientific meeting experience. These results also guided the development of a more streamlined survey for use in future years. Copyright © 2017 the American Physiological Society.

    Warland, Jane; McKellar, Lois; Diaz, Monica

    2014-11-01

    Assertiveness can be defined as an interpersonal behaviour that promotes the fact all people in a relationship are equally important. All health professionals including midwives must work with and care for people. At times this will include facilitating interactions that require skilful negotiation and assertiveness. Yet embedding assertiveness education into undergraduate midwifery curricula has not been widely adopted. This paper explores one method of delivering assertiveness training in an undergraduate midwifery course and provides comment on the effectiveness of this strategy in developing assertiveness skills in a cohort of undergraduate midwifery students. We used an assertiveness survey which was administered immediately before and 3-4 months after an assertiveness training workshop. All students (n = 55) attending the training day were invited to participate. Of these 41 (77% response) chose to participate in the pre intervention survey and 32 participated (9 students lost to follow-up) in the follow up survey. There was an overall improvement in self-perceived assertiveness scores following the assertiveness training workshop. These findings provide encouraging evidence that educational institutions that offer specific and targeted assertiveness education will be rewarded with more assertive graduates.

  15. Engineering success: Undergraduate Latina women's persistence in an undergradute engineering program

    Science.gov (United States)

    Rosbottom, Steven R.

    The purpose and focus of this narrative inquiry case study were to explore the personal stories of four undergraduate Latina students who persist in their engineering programs. This study was guided by two overarching research questions: a) What are the lived experiences of undergraduate Latina engineering students? b) What are the contributing factors that influence undergraduate Latina students to persist in an undergraduate engineering program? Yosso's (2005) community cultural wealth was used to the analyze data. Findings suggest through Yosso's (2005) aspirational capital, familial capital, social capital, navigational capital, and resistant capital the Latina student persisted in their engineering programs. These contributing factors brought to light five themes that emerged, the discovery of academic passions, guidance and support of family and teachers, preparation for and commitment to persistence, the power of community and collective engagement, and commitment to helping others. The themes supported their persistence in their engineering programs. Thus, this study informs policies, practices, and programs that support undergraduate Latina engineering student's persistence in engineering programs.

  16. NSF Support for Physics at the Undergraduate Level: A View from Inside

    Science.gov (United States)

    McBride, Duncan

    2015-03-01

    NSF has supported a wide range of projects in physics that involve undergraduate students. These projects include NSF research grants in which undergraduates participate; Research Experiences for Undergraduates (REU) centers and supplements; and education grants that range from upper-division labs that may include research, to curriculum development for upper- and lower-level courses and labs, to courses for non-majors, to Physics Education Research (PER). The NSF Divisions of Physics, Materials Research, and Astronomy provide most of the disciplinary research support, with some from other parts of NSF. I recently retired as the permanent physicist in NSF's Division of Undergraduate Education (DUE), which supports the education grants. I was responsible for a majority of DUE's physics grants and was involved with others overseen by a series of physics rotators. There I worked in programs entitled Instrumentation and Laboratory Improvement (ILI); Course and Curriculum Development (CCD); Course, Curriculum, and Laboratory Improvement (CCLI); Transforming Undergraduate STEM Education (TUES); and Improving Undergraduate STEM Education (IUSE). NSF support has enabled physics Principal Investigators to change and improve substantially the way physics is taught and the way students learn physics. The most important changes are increased undergraduate participation in physics research; more teaching using interactive engagement methods in classes; and growth of PER as a legitimate field of physics research as well as outcomes from PER that guide physics teaching. In turn these have led, along with other factors, to students who are better-prepared for graduate school and work, and to increases in the number of undergraduate physics majors. In addition, students in disciplines that physics directly supports, notably engineering and chemistry, and increasingly biology, are better and more broadly prepared to use their physics education in these fields. I will describe NSF

    2008-09-01

    The purpose of this literature review was to ascertain the evidence for the use of reflective journaling as a tool to promote the pedagogical strategy of reflection for the purpose of learning from practice for practice in undergraduate nursing education. Concept-centric. The literature review involved structured searches of all OVID gateway databases, EBSCO host databases, and Blackwell Synergy. Qualitative and Quantitative Studies from 1992 to 2006 were included if they focused on reflective journaling in undergraduate clinical education. Due to the vast plethora of literature on reflection, keywords were utilized to focus the search. Approximately 150 abstracts were reviewed for primary sources of research. A total of nine studies met the inclusion criteria. The review subsequently divided the literature into four content themes allowing for appraisal and analysis of the findings, followed by summary and key recommendations for nursing education and research. There was evidence that educators struggle to incorporate reflective processes into education; however, the research provided rationale and support for engaging undergraduate students in the reflective process. Researchers found reasonable levels of reflection in undergraduate students' journaling and educators reported students' learning as a result of reflective journaling. Further to this, there was evidence that writing reflectively improved over time; a learned skill also dependent on a good facilitator and trust. Unfortunately, there was a paucity of research that explored the undergraduate nurses' experiences with the process of having to create written communication, with a critical reflective focus on practice. Nursing educators are correct in pursuing the teaching and learning of the reflective process in undergraduate nursing education. Nurse educators need to utilize various tools and strategies for facilitating the growth of undergraduate students into reflective practitioners. Indeed there was

    2014-01-01

    Full Text Available In modern society, undergraduates may encounter multiple pressures and thus feel the sense of alienation, anxiety, disturbance and depression. For undergraduates, reading can be independently conducted without the intervention of an instructor; therefore, undergraduates who feel reluctant to expose private emotions to counselors can help themselves through the reading of emotional healing books. This is the application of bibliotherapy. Among various resources, fiction can serve as an appropriate emotional reading material. The researcher deployed semi-structured in-depth interview, and interviewed 21 undergraduates in Taipei City and Taipei County. This study is aimed to understand the kinds of fictions undergraduates read when they are upset and to analyze the emotional healing process of identification, catharsis, and insight so that the emotional healing efficacy can be evaluated. The findings showed that romance, realistic fiction, fantasy, martial arts novel, inspirational fiction, historical fiction, and science fiction can provide full process of emotional healing efficacy. However, detective fiction, online novel, psychological fiction, and horror fiction can only provide parts of the healing process. Besides, the healing efficacy of a specific fiction is different from reader to reader.

    NOAA supports about 115 - 150 undergraduates per year through the Ernest F. Hollings Scholarship and the Educational Partnership Program Undergraduate Scholarship. These programs provide tuition support and paid summer internships at NOAA to exceptional students majoring in the geosciences. Multiple methods were used to evaluate program outcomes and track the career trajectories, including mining LinkedIn data and conducting evaluation surveys of recipients as well as students who applied but did not receive the award. Results show more than 75% of scholars continued on to graduate school, primarily in a NOAA mission fields. This compared to only 56% of nonrecipients. More than 60% of alumni had at least one professional record, with the most alumni working in private industry, followed by nongovernmental organizations and federal, state and local government. The evaluation identified 77 other scholarship programs applied to by NOAA scholarship recipients. The most commonly reported program was the NSF Research Experiences for Undergraduates (REU) for which 20% of scholars applied and 46% of applications were successful. Other common scholarships included the Goldwater Scholarship (received by 5% of NOAA scholars) and the Udall Scholarship (received by 4% of scholars). In the most recent class of 118 undergraduate scholars, 24% reported having another research experience by the time they arrived for orientation at the end of their sophomore year. These results suggest coordination across scholarship opportunities may be useful to engage and retain students in geoscience fields.

    Full Text Available Kunj Patel, Omar El Tokhy Faculty of Medicine, Imperial College London, London, UKWe read with great interest the study by Frost et al1 which highlights the importance of scenario-based teaching (SBT of clinical communication in medical undergraduate pediatrics teaching. SBT involves students navigating a storyline based around a complex problem, running in parallel with case-based learning. We were impressed by the results of the SBT program at Cardiff University School of Medicine. As medical students currently on our pediatric rotation at Imperial College London, we have experienced at first hand the benefits of SBT. Throughout the placement, it continues to help us tackle the complexities which arise when communicating with children and their families. We have noted its particular benefit in breaking bad news to families. Without effective teaching on this particular scenario, a failure to grasp this skill could exacerbate patient and parent concerns. Much like the authors of this study highlight,1 we believe specific teaching on communication skills should be a mandatory part of medical undergraduate education at every institution. Imperial College School of Medicine has developed a similar teaching style which has been unparalleled in its benefit to us during our pediatric rotation. Although there is scant literature available specifically addressing communicating with children and parents at undergraduate level, the use of SBT throughout undergraduate medical teaching should not be underestimated. Read the original paper by Frost et al

    2014-01-01

    Over its nearly 20 year history the WIYN Observatory has provided crucial data for numerous undergraduate research projects at the partner institutions (University of Wisconsin-Madison, Indiana University, and Yale University) plus others who access the telescope via national time from NOAO. WIYN and its instruments have served both undergraduates who are local to each institution, as well as those who have a temporary tenure as Research Experience for Undergraduates (REU) students. The topics of this work range widely, and only a few examples are listed here. Numerous studies of stars have been undertaken by undergraduates, from rotation velocities of pre-main sequence stars (Rhode et al.) to dynamical heating mechanisms in open clusters (Friel et al.). Extragalactic investigations range from a study of cold ISM in galaxies near the centers of rich clusters (Gallagher & Hooper, et al.) to the stellar populations of post-starburst galaxies hosting low-level AGN (Wolf & Hooper, et al.). Students have made wide use of WIYN's long established suite of facility instruments, which currently includes the Hydra multi-object fiber spectrograph, the SparsePak integral field unit fiber spectrograph, and the WHIRC near-infrared imager. A current undergraduate is a key player in final laboratory testing of two new integral field units that will come to WIYN soon. Finally, the new large format imager pODI currently is in science operation, soon to be followed by an upgrade to nearly four times the current imaging area, a powerful tool that will join the others in contributing to undergraduate research and education. This presentation is a continuation of the overview of WIYN contributions to education that began with a discussion of graduate education at the Indianapolis AAS (Hooper, AAS Meeting #222, #214.23).

    Shillenn, J.K.; Klevans, E.H.

    1988-01-01

    Maintaining a reliable pool of qualified nuclear engineering graduates depends on the ability of nuclear engineering undergraduate programs to recruit students. With the prospect of declining enrollments in nuclear engineering it is important for nuclear engineering programs to know what factors influence students to choose nuclear engineering as an undergraduate major and why they choose a particular undergraduate program. This type of information can be very important to nuclear engineering programs that develop recruiting strategies. To provide some insight into this area, a questionnaire was designed and given to undergraduate nuclear engineering students at Pennsylvania State University. The purpose of the survey was to provide information on the reasons that students picked nuclear engineering as a career and chose to attend Penn State. The questionnaire was given to 27 students in their junior year during the spring semester of 1987 and again to 35 junior students during the spring semester of 1988. There was little difference except as noted between the two groups on their responses to the questionnaire. A partial listing of the survey results is provided

    The effect of scientific training on course learning in undergraduates is still controversial. In this study, we investigated the academic performance of undergraduate students with and without scientific training. The results show that scientific training improves students' test scores in general medical courses, such as biochemistry and molecular biology, cell biology, physiology, and even English. We classified scientific training into four levels. We found that literature reading could significantly improve students' test scores in general courses. Students who received scientific training carried out experiments more effectively and published articles performed better than their untrained counterparts in biochemistry and molecular biology examinations. The questionnaire survey demonstrated that the trained students were more confident of their course learning, and displayed more interest, motivation and capability in course learning. In summary, undergraduate academic performance is improved by scientific training. Our findings shed light on the novel strategies in the management of undergraduate education in the medical school. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(5):379-384, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

    Kinard, W.F.

    1993-01-01

    A large fraction of the potential graduate students in chemistry come from undergraduate colleges. The exposure of these students to the field of nuclear and radiochemistry is limited by the fact that few professionals actively involved in the field teach at these schools. There is also increasing competition for the limited number of chemistry students by other chemical specializations. Innovative approaches such as a short course to introduce students to nuclear and radiochemistry and some of the needs for undergraduate teaching are discussed. (author) 6 refs.; 2 figs

  7. Teaching undergraduate biomechanics with Just-in-Time Teaching.

    Riskowski, Jody L

    2015-06-01

    Biomechanics education is a vital component of kinesiology, sports medicine, and physical education, as well as for many biomedical engineering and bioengineering undergraduate programmes. Little research exists regarding effective teaching strategies for biomechanics. However, prior work suggests that student learning in undergraduate physics courses has been aided by using the Just-in-Time Teaching (JiTT). As physics understanding plays a role in biomechanics understanding, the purpose of study was to evaluate the use of a JiTT framework in an undergraduate biomechanics course. This two-year action-based research study evaluated three JiTT frameworks: (1) no JiTT; (2) mathematics-based JiTT; and (3) concept-based JiTT. A pre- and post-course assessment of student learning used the biomechanics concept inventory and a biomechanics concept map. A general linear model assessed differences between the course assessments by JiTT framework in order to evaluate learning and teaching effectiveness. The results indicated significantly higher learning gains and better conceptual understanding in a concept-based JiTT course, relative to a mathematics-based JiTT or no JiTT course structure. These results suggest that a course structure involving concept-based questions using a JiTT strategy may be an effective method for engaging undergraduate students and promoting learning in biomechanics courses.

  8. Investigating Undergraduate Science Students’ Conceptions and Misconceptions of Ocean Acidification

    2015-01-01

    Scientific research exploring ocean acidification has grown significantly in past decades. However, little science education research has investigated the extent to which undergraduate science students understand this topic. Of all undergraduate students, one might predict science students to be best able to understand ocean acidification. What conceptions and misconceptions of ocean acidification do these students hold? How does their awareness and knowledge compare across disciplines? Undergraduate biology, chemistry/biochemistry, and environmental studies students, and science faculty for comparison, were assessed on their awareness and understanding. Results revealed low awareness and understanding of ocean acidification among students compared with faculty. Compared with biology or chemistry/biochemistry students, more environmental studies students demonstrated awareness of ocean acidification and identified the key role of carbon dioxide. Novel misconceptions were also identified. These findings raise the question of whether undergraduate science students are prepared to navigate socioenvironmental issues such as ocean acidification.

    Science.gov (United States)

    Wang, Jack T H

    2017-08-15

    Inquiry-driven learning, research internships and course-based undergraduate research experiences all represent mechanisms through which educators can engage undergraduate students in scientific research. In life sciences education, the benefits of undergraduate research have been thoroughly evaluated, but limitations in infrastructure and training can prevent widespread uptake of these practices. It is not clear how faculty members can integrate complex laboratory techniques and equipment into their unique context, while finding the time and resources to implement undergraduate research according to best practice guidelines. This review will go through the trends and patterns in inquiry-based undergraduate life science projects with particular emphasis on molecular biosciences-the research-aligned disciplines of biochemistry, molecular cell biology, microbiology, and genomics and bioinformatics. This will provide instructors with an overview of the model organisms, laboratory techniques and research questions that are adaptable for semester-long projects, and serve as starting guidelines for course-based undergraduate research. © FEMS 2017.

    Studies have found that although there are high rates of depression among university students, their help-seeking practices are poor. It is important to identify students who are less likely to seek the necessary help, to encourage better help-seeking among them. This study, which was conducted among undergraduates in Sri Lanka, examined the associations between personal characteristics of the undergraduates and their intentions to seek help for depression. This was a cross-sectional study in which 4461 undergraduates (Male: n = 1358, 30.4%, Female: n = 3099, 69.5%; Mean age = 22.18; SD = 1.47) indicated their intentions to seek help if personally affected by depression, which was described in a hypothetical vignette about a peer experiencing depression symptomatology. The predictors of the undergraduates' help-seeking intentions, including their sociodemographic characteristics, prior exposure to and recognition of the problem, and their stigma towards those with depression were examined using binary logistic regression analyses models. The undergraduates' ability to recognise the problem was one of the strongest predictors of their intentions to seek professional help. Those with higher levels of stigma were less likely to seek both professional and informal help. While females were less likely to consider professional help, they were more likely to consider the help of informal help-providers and to consider religious strategies. Medical undergraduates and those who had sought help for personal experiences of the problem were also more likely to consider informal help. However, all these associations resulted in small effect sizes, except for those between recognition of the problem and the undergraduates' intentions to seek professional help, where medium to very large effect sizes were observed in the case of some the associations examined. Improvement of problem-recognition may be a key strategy for improving help-seeking among these

    Full Text Available The goal of this study was to evaluate skeletal, dental and chronological development in an HIV-positive group of children, as compared with a control group, during a four-year period. Panoramic radiographs and hand and wrist radiographs of 60 children were taken. The children, of both sexes, aged 5 years and 2 months to 15 years and 5 months, were selected as follows: 30 HIV-positive volunteers who had acquired the disease vertically, and 30 volunteers who did not present the HIV infection or any other systemic disease. All radiographs were technically standardized and analyzed according to criteria established by Nolla (dental age, Greulich and Pyle (bone age, and Eklöf and Ringertz (bone age. The results were submitted to Student's t-test at a 5% level of significance. Based on the comparison between the chronological age and the dental or the skeletal age, significant differences were observed between HIV-positive and HIV-negative children, both in 1999 and in 2003 (p Este trabalho teve como objetivo avaliar, em um intervalo de quatro anos, o desenvolvimento ósseo, dentário e cronológico de um grupo de crianças portadoras do HIV, comparando-o com um grupo controle.

    Eastwood, Kathryn; Boyle, Malcolm J; Williams, Brett

    2012-01-01

    BACKGROUND: Previous investigation of drug calculation skills of qualified paramedics has highlighted poor mathematical ability with no published studies having been undertaken on undergraduate paramedics. There are three major error classifications. Conceptual errors involve an inability to formulate an equation from information given, arithmetical errors involve an inability to operate a given equation, and finally computation errors are simple errors of addition, subtraction, division and multiplication. The objective of this study was to determine if undergraduate paramedics at a large Australia university could accurately perform common drug calculations and basic mathematical equations normally required in the workplace. METHODS: A cross-sectional study methodology using a paper-based questionnaire was administered to undergraduate paramedic students to collect demographical data, student attitudes regarding their drug calculation performance, and answers to a series of basic mathematical and drug calculation questions. Ethics approval was granted. RESULTS: The mean score of correct answers was 39.5% with one student scoring 100%, 3.3% of students (n=3) scoring greater than 90%, and 63% (n=58) scoring 50% or less, despite 62% (n=57) of the students stating they ‘did not have any drug calculations issues’. On average those who completed a minimum of year 12 Specialist Maths achieved scores over 50%. Conceptual errors made up 48.5%, arithmetical 31.1% and computational 17.4%. CONCLUSIONS: This study suggests undergraduate paramedics have deficiencies in performing accurate calculations, with conceptual errors indicating a fundamental lack of mathematical understanding. The results suggest an unacceptable level of mathematical competence to practice safely in the unpredictable prehospital environment. PMID:25215067

  5. Time and space: undergraduate Mexican physics in motion

    2010-09-01

    This is an ethnographic study of the trajectories and itineraries of undergraduate physics students at a Mexican university. In this work learning is understood as being able to move oneself and, other things (cultural tools), through the space-time networks of a discipline (Nespor in Knowledge in motion: space, time and curriculum in undergraduate physics and management. Routledge Farmer, London, 1994). The potential of this socio-cultural perspective allows an analysis of how students are connected through extended spaces and times with an international core discipline as well as with cultural features related to local networks of power and construction. Through an example, I show that, from an actor-network-theory (Latour in Science in action. Harvard University Press, Cambridge, 1987), that in order to understand the complexities of undergraduate physics processes of learning you have to break classroom walls and take into account students' movements through complex spatial and temporal traces of the discipline of physics. Mexican professors do not give classes following one textbook but in a moment-to-moment open dynamism tending to include undergraduate students as actors in classroom events extending the teaching space-time of the classroom to the disciplinary research work of physics. I also find that Mexican undergraduate students show initiative and display some autonomy and power in the construction of their itineraries as they are encouraged to examine a variety of sources including contemporary research articles, unsolved physics problems, and even to participate in several physicists' spaces, as for example being speakers at the national congresses of physics. Their itineraries also open up new spaces of cultural and social practices, creating more extensive networks beyond those associated with a discipline. Some economic, historical and cultural contextual features of this school of sciences are analyzed in order to help understanding the particular

    Full Text Available The University of Alberta Libraries (UAL, working with two book vendors, created large-scale undergraduate book approval plans to deliver new publications. Detailed selections profiles were created for many subject areas, designed to deliver books that would have been obvious choices by subject selectors. More than 5800 monographs were received through the book approval plans during the pilot period. These volumes proved to be highly relevant to users, showing twice as much circulation as other monographs acquired during the same time period. Goals achieved through this project include: release of selectors’ time from routine work, systematic acquisition of a broadly based high-demand undergraduate collection and faster delivery of undergraduate materials. This successful program will be expanded and incorporated into UAL’s normal acquisitions processes for undergraduate materials.

    Many undergraduate research training programs incorporate research ethics into their programs and some are required. Engaging students in conversations around challenging topics such as conflict of interest, cultural and gender biases, what is science and what is normative science can difficult in newly formed student cohorts. In addition, discussing topics with more distant impacts such as science and policy, intellectual property and authorship, can be difficult for students in their first research experience that have more immediate concerns about plagiarism, data manipulation, and the student/faculty relationship. Oregon State University's Research Experience for Undergraduates (REU) in Ocean Sciences: From Estuaries to the Deep Sea as one model for incorporating a research ethics component into summer undergraduate research training programs. Weaved into the 10-week REU program, undergraduate interns participate in a series of conversations and a faculty mentor panel focused on research ethics. Topics discussed are in a framework for sharing myths, knowledge and personal experiences on issues in research with ethical implications. The series follows guidelines and case studies outlined from the text, On Being A Scientist: Responsible Conduct In Research Committee on Science, Engineering, and Public Policy, National Academy of Sciences.

    Paralleling the explosive growth of neuroscientific knowledge over the last two decades, numerous institutions from liberal arts colleges to research universities have either implemented or begun exploring the possibility of implementing undergraduate programs in neuroscience. In 1995, Faculty for Undergraduate Neuroscience (FUN) partnered with Project Kaleidoscope (PKAL) to offer a workshop exploring how undergraduate neuroscience education should proceed. Four blueprints were created to provide direction to the burgeoning interest in developing programs in undergraduate neuroscience education: 1) Neuroscience nested in psychology; 2) Neuroscience nested in biology; 3) Neuroscience as a minor; and 4) Neuroscience as a major. In 2005, FUN again partnered with PKAL to revisit the blueprints in order to align the blueprints with modern pedagogical philosophy and technology. The original four blueprints were modified and updated. One particularly exciting outgrowth of the 2005 workshop was the introduction of a fifth curricular blueprint that strongly emphasizes the integration of the humanities and social sciences into neuroscience: Neuroscience Studies. Because of the interdisciplinary nature of neuroscience, an education in neuroscience will prepare the next generation of students to think critically, synthetically, and creatively as they confront the problems facing humanity in the 21(st) century.

    This explanatory study examines three focal periods in undergraduate STEM as related to the gender gap. Social, economic, and more general historical data are used to develop a clear and powerful explanation of baccalaureate trends in biology and engineering. Specifically, historical accounts are offered for 1) a ten-year period in undergraduate biology in which the number of baccalaureates awarded to men decreased 44 percent, while the number of baccalaureates awarded to women decreased one percent; 2) the start of a twenty-year period in which the number of bachelor's degrees awarded in the biological sciences increased 150 percent---from 36,068 degrees in 1989, to 90,003 bachelor's degrees in 2011; and 3) a ten year period in undergraduate engineering where female graduation rates septupled---this ten-year time period is the only instance of meaningful and noteworthy growth for women in undergraduate engineering over the past half century. Findings from each history reveal a common narrative underlying baccalaureate trends. Implications for undergraduate STEM are discussed.

    2013-01-01

    Full Text Available The paper maintains that for developing the educational pro- grams and technologies adequate to the different stages of students’ growth and maturity, there is a need for exploring the natural determinants of intel- lectual development as well as the students’ individual qualities affecting the cognition process. The authors investigate the differences of the intellect manifestations with the reference to the gender principle, and analyze the correlations be- tween verbal and non-verbal components in boys and girls’ mental activity depending on their general intellect potential. The research, carried out in Si- berian State Automobile Road Academy and focused on the first year stu- dents, demonstrates the absence of gender differences in students’ general in- tellect levels; though, there are some other conformities: the male students of different intellectual levels show the same correlation coefficient of verbal and non-verbal intellect while the female ones have the same correlation only at the high intellect level. In conclusion, the authors emphasize the need for the integral ap- proach to raising students’ mental abilities considering the close interrelation between the verbal and non-verbal component development. The teaching materials should stimulate different mental qualities by differentiating the educational process to develop students’ individual abilities.

    Young, Christina B; Fang, Daniel Z; Zisook, Sidney

    2010-09-01

    Depression is a serious and often under-diagnosed and undertreated mental health problem in college students which may have fatal consequences. Little is known about ethnic differences in prevalence of depression in US college campuses. This study compares depression severity in Asian-American and Caucasian undergraduate students at the University of California San Diego (UCSD). Participants completed the nine item Patient Health Questionnaire and key demographic information via an anonymous online questionnaire. Compared to Caucasians, Asian-Americans exhibited significantly elevated levels of depression. Furthermore, Korean-American students were significantly more depressed than Chinese-American, other minority Asian-American, and Caucasian students. In general, females were significantly more depressed than males. Results were upheld when level of acculturation was considered. The demographic breakdown of the student population at UCSD is not representative to that of the nation. These findings suggest that outreach to female and Asian-American undergraduate students is important and attention to Korean-American undergraduates may be especially worthwhile. 2010 Elsevier B.V.

    The National Science Foundation's 1996 report "Shaping the Future: New Expectations for Undergraduate Education in Science, Mathematics, Engineering and Technology" urged that in order to improve SME&T education, decisive action must be taken so that "all students have access to excellent undergraduate education in science .... and all students learn these subjects by direct experience with the methods and processes of inquiry." Research-related educational activities that integrate education and research have been shown to be valuable in improving the quality of education and enhancing the number of majors in physics departments. Student researchers develop a motivation to continue in science and engineering through an appreciation of how science is done and the excitement of doing frontier research. We will address some of the challenges of integrating research into the physics undergraduate curriculum effectively. The departmental and institutional policies and infrastructure required to help prepare students for this endeavor will be discussed as well as sources of support and the establishment of appropriate evaluation procedures.

    2010-07-01

    Mechanical damage in transportation pipelines is an issue of extreme importance to pipeline operators and many others. Appropriate procedures for severity assessment are necessary. This paper mainly studies the effect of geometry, material and pressure variability on strain and stress fields in dented pipelines subjected to static and cyclic pressure. Finite element analysis (FEA) has often been used to overcome the limitations of a full-scale test, but it is still impossible to run FEA for all possible combinations of parameters. Probabilistic analysis offers an excellent alternative method to determine the sensitivity of the strain and stress fields to each of those input parameters. A hundred cases were randomly generated with Monte Carlo simulations and analyzed, a general formula was proposed to relate the output variables in terms of practically measured variables, and regression analysis was performed to confirm the appropriateness of the general formula.

  6. Music Undergraduates' Usefulness and Importance Expectations: The Bologna Process from an Australian University Perspective.

    Science.gov (United States)

    Harvey, Dominic G; Davidson, Jane W; Nair, Chenicheri S

    2016-01-01

    The Bologna Process model of higher education has been introduced into some Australian universities since 2008. This model promoted university study through a liberal arts philosophy that advanced a worldview approach at the undergraduate level. The model generalized the student experience and eliminated undergraduate specialization. An interesting situation for music undergraduate study thus arose. Expertise and expert performance research has argued an opposing educational approach, namely: Extensive long-term commitment through focused practical engagement and specialized tuition as prerequisites to achieving musical mastery, especially in performance. Motivation research has shown that the majority of this specialized development in pre-university years would be accessed and reinforced predominantly through private music tuition.

    The Bologna Process model of higher education has been introduced into some Australian universities since 2008. This model promoted university study through a liberal arts philosophy that advanced a worldview approach at the undergraduate level. The model generalized the student experience and eliminated undergraduate specialization. An interesting situation for music undergraduate study thus arose. Expertise and expert performance research has argued an opposing educational approach, namely: Extensive long-term commitment through focused practical engagement and specialized tuition as prerequisites to achieving musical mastery, especially in performance. Motivation research has shown that the majority of this specialized development in pre-university years would be accessed and reinforced predominantly through private music tuition. Drawing on this contextual literature, commencing university music undergraduates would have expectations of their prospective study founded from two historical influences.

    Full Text Available The purpose of this research was to evaluate the diffusion of calcium (Ca+2 and hydroxyl (OH- ions from materials with a calcium hydroxide base - Ca(OH2 through the intact roots of deciduous teeth. This diffusion of ions is important for periapical healing. Forty-six deciduous teeth were selected and instrumented to their working length with #40 files. The teeth were washed during cleaning and shaping with a 1% sodium hypochlorite (NaOCl solution. The canals were dried with paper points. The teeth were divided into 4 groups based on the sealer type, with 10 specimens in each group. A fifth group of 6 teeth without sealer constituted the control group. The materials used as sealers were: Ca(OH2 paste associated to propylene glycol (CaPE thickened at the proportion of 2:1 w/v; UFSC (Federal University of Santa Catarina paste - a mixture of 0.3g of zinc oxide with 0.3g of Ca(OH2 with 0.2ml of olive oil 1:1 w/w; Vitapex® and Sealapex®. The coronal access was sealed with a glass ionomer after the root had been filled with each sealer. A one-third apical surface and foramen was hard-pressed with Araldite®. The teeth were stored individually in flasks containing saline solution at 37ºC and 100% humidity. The OH- and Ca+2 ions diffusion levels were determined using a pH meter and an atomic absorption spectrometer. Data were collected at 48 hours and at intervals of 7, 30, 45 and 60 days.

    Krishnan, Shankar M

    2014-01-01

    There is a proliferation of medical devices across the globe for the diagnosis and therapy of diseases. Biomedical engineering (BME) plays a significant role in healthcare and advancing medical technologies thus creating a substantial demand for biomedical engineers at undergraduate and graduate levels. There has been a surge in undergraduate programs due to increasing demands from the biomedical industries to cover many of their segments from bench to bedside. With the requirement of multidisciplinary training within allottable duration, it is indeed a challenge to design a comprehensive standardized undergraduate BME program to suit the needs of educators across the globe. This paper's objective is to describe three major models of undergraduate BME programs and their curricular requirements, with relevant recommendations to be applicable in institutions of higher education located in varied resource settings. Model 1 is based on programs to be offered in large research-intensive universities with multiple focus areas. The focus areas depend on the institution's research expertise and training mission. Model 2 has basic segments similar to those of Model 1, but the focus areas are limited due to resource constraints. In this model, co-op/internship in hospitals or medical companies is included which prepares the graduates for the work place. In Model 3, students are trained to earn an Associate Degree in the initial two years and they are trained for two more years to be BME's or BME Technologists. This model is well suited for the resource-poor countries. All three models must be designed to meet applicable accreditation requirements. The challenges in designing undergraduate BME programs include manpower, facility and funding resource requirements and time constraints. Each academic institution has to carefully analyze its short term and long term requirements. In conclusion, three models for BME programs are described based on large universities, colleges, and

    Undergraduate involvement in research has the potential to advance science, enhance education, strengthen the research community, and raise general awareness of the importance and impact of scientific understanding. Rather than being competing objectives, these goals are synergistic. Effective research experiences are those that create win-win-win situations: benefits to the student, benefits to the project, and benefits to the scientific community. When structured appropriately, undergraduate research fits into a learner-centered paradigm that puts emphasis on student learning, rather than instructor teaching. Under such a paradigm the student and professor learn together, constructing knowledge by integrating information with critical-thinking and problem-solving skills, and use this knowledge to address issues in real-life contexts. Creating such a learning environment requires that the professor be vested in the outcome of the research, that the student take a meta-cognitive approach to the project and work at a level appropriate to her abilities, and that the student understand how her contribution fits into the project and the larger field. All of these factors lead to greater independence, confidence, and productivity on the part of the student. By providing undergraduates with these experiences, we introduce not only future scientists but also non-scientists to the excitement of discovery and the value of scientific research. Currently, we involve undergraduates in our research on the hydrology and geochemistry of a tropical montane cloud forest in Monteverde, Costa Rica. At the start of each student's involvement, we provide her with the big picture: our project goals, the relevant social issues, and the importance of watershed research. Each student then articulates her own educational and project objectives. Together, we choose tasks that match her skills and interests with our scholarly work. Specific activities range from literature review to

    Mukundu Nagesh, Navin; Chiva Giurca, Bogdan; Lishman, Suzy

    2018-05-01

    The trends in modern undergraduate medical education focus on a patient-centred approach through problem-based learning over the traditional modular curriculum. Integrating pathology into this style of learning has resulted in the dilution of core scientific principles which may have contributed to reduced understanding and interest in the subject. We aim to innovate pathology education by utilising National Pathology Week which is organised by the Royal College of Pathologists to develop the public engagement model which empowers students to learn pathology by teaching the public. Through this model, we hope to generate a greater interest in pathology at both undergraduate and postgraduate stages of education. We obtained funding from the Royal College of Pathologists to organise National Pathology Week at Exeter Medical School and the Royal Devon & Exeter Hospital. We involved 125 undergraduate student volunteers from health-related courses. We designed a curriculum aiming to educate both students and public on current topics such as cancer screening programmes, antibiotic resistance, diagnosis of inflammatory bowel disease and the role of pathologists. We hosted 15 pathologists, biomedical scientists and microbiologists to engage with students, share experiences and offer an insight into their careers. Through this project, we interacted with over 500 members of the public and 150 school students. The medical student volunteers developed a range of skills including competent use of microscopes to visualise pathology slides, effective communication with lay audiences to teach pathology and understanding of the clinical application of pathology. We believe the public engagement model of teaching undergraduate students has the potential to develop a greater interest in pathology whilst benefitting the wider community.

    The safety of patients consulting with practitioners of complementary and alternative medicine (CAM) partially depends on practitioners' competence, and thus the standard of undergraduate education. Describe undergraduate homeopathy courses in Europe, student/graduate numbers and whether there were differences between recognised/accredited and non-recognised/non-accredited courses. Cross sectional survey of current homeopathy undergraduate education in Europe in 2008. Data from 145 (94.8%) out of 153 identified courses were collected. Eighty-five (55.6%) responded to a questionnaire survey. For others some data was extracted from their websites. Only data from the questionnaire survey is used for the main analysis. The average course in the questionnaire survey had 47 enrolled students and 142 graduates, and lasted 3.6 years part-time. An estimated 6500 students were enrolled and 21,000 had graduated from 153 identified European undergraduate homeopathy courses. Out of 85 courses most had entry requirements and provided medical education (N = 48) or required students to obtain this competence elsewhere (N = 33). The average number of teaching hours were 992 (95% confidence interval (CI) 814, 1170) overall, with 555 h (95%CI 496, 615) for homeopathy. Four out of five courses were recognised/accredited. Recognised/accredited part-time courses lasted significantly longer than non-recognised/non-accredited courses (difference 0.6 years, 95%CI 0.0-1.2, P = 0.040), and offered significantly larger numbers of teaching hours in homeopathy (difference 167 h, 95%CI 7-327, P = 0.041). About 6500 currently enrolled students are doing undergraduate homeopathy education in Europe and 21,000 have graduated from such courses over a period of about 30 years. Undergraduate homeopathy education in Europe is heterogeneous. Recognised/accredited courses are more extensive with more teaching hours. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2011-06-01

    Full Text Available The relationships between personality and career decision making in undergraduates are analyzed in this work. The hypothesis is that efficient personality is associated with the more mature process of career decision making. For this hypothesis, the Questionnaire of Efficient Personality and the Inventory of Career Factors was administered to 497 students in their final year of undergraduate school. The collected data was put under factorial analysis, analysis of differences of averages, and analysis of variance. The results confirm that an effective personality is tied to career decision making based as much on one´s knowledge of oneself as an understanding of the working world.

  1. Providing Real Research Opoportunities to Undergraduates

    2016-01-01

    The current approach to undergraduate education focuses on teaching classes which provide the foundational knowledge for more applied experiences such as scientific research. Like most programs, Florida Institute of Technology (Florida Tech or FIT) strongly encourages undergraduate research, but is dominated by content-focused courses (e.g., "Physical Mechanics"). Research-like experiences are generally offered through "lab" classes, but these are almost always reproductions of past experiments: contrived, formulaic, and lacking the "heart" of real (i.e., potentially publishable) scientific research. Real research opportunities 1) provide students with realistic insight into the actual scientific process; 2) excite students far more than end-of-chapter problems; 3) provide context for the importance of learning math, physics, and astrophysics concepts; and 4) allow unique research progress for well-chosen problems. I have provided real research opportunities as an "Exoplanet Lab" component of my Introduction to Space Science (SPS1020) class at Florida Tech, generally taken by first-year majors in our Physics, Astronomy & Astrophysics, Planetary Science, and Astrobiology degree programs. These labs are a hybrid between citizen science (e.g., PlanetHunters) and simultaneously mentoring ~60 undergraduates in similar small research projects. These projects focus on problems that can be understood in the context of the course, but which benefit from "crowdsourcing". Examples include: dividing up the known planetary systems and developing a classification scheme and organizing them into populations (Fall 2013); searching through folded light curves to discover new exoplanets missed by previous pipelines (Fall 2014); and fitting n-body models to all exoplanets with known Transit Timing Variations to estimate planet masses (Fall 2015). The students love the fact that they are doing real potentially publishable research: not many undergraduates can claim to have discovered

    Smoking is one of the major Public Health problems worldwide. To study the frequency of tobacco smoking among undergraduate students of a Chilean university. An opinion survey was sent by e-mail to all undergraduate students of a university, registering gender, age, study years, study area, smoking behavior, motivation (reason for smoking), intention to quit and tobacco law perception. 1,008 (57% females) out of 11,679 surveys were answered back. Prevalence of active smoking among respondents was 36%, without association with gender, age or years of study. However, students from scientific areas had a lower prevalence. Seventy seven percent of smokers manifested the intention to quit the habit or have started quitting already. Ninety six percent were acquainted with the tobacco law and by 73% agreed with it. Smoking is highly prevalent among university students. It is necessary to develop strategies for smoking cessation within universities that may prevent or reduce tobacco smoking among students.

    Steane, Andrew M

    2016-01-01

    This is an undergraduate textbook in thermodynamics—the science of heat, work, temperature, and entropy. The text presents thermodynamics in and of itself, as an elegant and powerful set of ideas and methods. These methods open the way to understanding a very wide range of phenomena in physics, chemistry, engineering, and biology. Starting out from an introduction of concepts at first year undergraduate level, the roles of temperature, internal energy, and entropy are explained via the laws of thermodynamics. The text employs a combination of examples, exercises, and careful discussion, with a view to conveying the feel of the subject as well as avoiding common misunderstandings. The Feynman–Smuluchowski ratchet, Szilard’s engine, and Maxwell’s daemon are used to elucidate entropy and the second law. Free energy and thermodynamic potentials are discussed at length, with applications to solids as well as fluids and flow processes. Thermal radiation is discussed, and the main ideas significant to global...

    There are deficiencies on Intensive Medicine (IM) teaching in most of medical undergraduate schools. Those deficiencies may imply damages on their clinical competence. The objective of this study was to analyze current status of IM teaching and the medical undergraduate student interest in this speciality. A cross-sectional study was performed in 2005. We applied a self-reported questionnaire to enrolled students between the sixth and the last semesters of two medical schools from Salvador-Bahia. The questionnaire contained questions about students' interest and knowledge on IM, and opinion on IM teaching in their schools. We studied 570 students. Most of them (57.5%) had never realized a clerkship in intensive care unit (ICU) despite classifying its usefulness as high (mean of 4.14 ± 1.05, in a scale from 1 to 5). IM interest was high or very high in 53.7% of sample. Almost all students (97%) thought that IM topics should be more explored at their curriculum. Only 42.1% reported to be able to assess a critical care patient and this assurance was higher among students with previous clerkship in ICU (p < 0.001). Shock, cardiopulmonary resuscitation and sepsis were the most interesting topics in ICU for students' opinion. This study revealed a high interest in IM among medical undergraduate students. However, most had never practice a clerkship in ICU, demonstrating to be an important factor on undergraduate student performance faced to a critical care patient.

The evaluation process for undergraduate distance education courses in the USA was evaluated by identifying those quality indicators adopted by international accreditation agencies. Based on the analysis of the evaluation process of distance undergraduate courses in Brazil, a further study was carried out about the results and impacts of the Brazilian system, especially the indicators used and the level of confidence that existed when measuring the quality of distance-based undergraduate courses. As a result of this research, our researchers observed there was a real need to establish a quality assurance benchmark in Brazil along these conceptual lines, namely one that represents quality in D.Ed. and includes the usage of indicators that reflect the excellence of the degree course that are offered. This level of excellence is assessed on the basis of the training, experience, knowledge and skills of the evaluators, as well as on clear, precise and transparent criteria for measuring the quality-based distance degree courses. On the other hand, it is also necessary to be equipped with a Bank of Evaluators – not only for those who work in this field, but also for a group of experts that is large enough to implement the Brazilian evaluation system in distance education programs.

    The Great Recession's influence on American undergraduate students' values was examined, testing Greenfield's and Kasser's theories concerning value development during economic downturns. Study 1 utilised aggregate-level data to investigate (a) population-level value changes between the pre-recession (2004-2006: n = 824,603) and recession freshman cohort (2008-2010: n = 662,262) and (b) overall associations of population-level values with national economic climates over long-term periods by correlating unemployment rates and concurrent aggregate-level values across 1966-2015 (n = 10 million). Study 2 examined individual-level longitudinal value development from freshman to senior year, and whether the developmental trajectories differed between those who completed undergraduate education before the Great Recession (freshmen in 2002, n = 12,792) versus those who encountered the Great Recession during undergraduate years (freshmen in 2006, n = 13,358). Results suggest American undergraduate students' increased communitarianism (supporting Greenfield) and materialism (supporting Kasser) during the Great Recession. The recession also appears to have slowed university students' development of positive self-views. Results contribute to the limited literature on the Great Recession's influence on young people's values. They also offer theoretical and practical implications, as values of this privileged group of young adults are important shapers of societal values, decisions, and policies. © 2016 International Union of Psychological Science.

  8. Plastic surgery in the undergraduate curriculum: the importance of considering students' perceptions.

    Burd, Andrew; Chiu, Tor; McNaught, Carmel

    2004-12-01

    As the undergraduate medical curriculum becomes increasingly crowded the competition for time inevitably increases and surgical specialties have decreasing representation. Plastic surgery is regarded with some confusion in terms of its relevance to the generic doctor. Plastic surgeons have no doubt about the relevance of the specialty to undergraduates. Others see this as a very technical specialty dealing with complex reconstructions and surgical interventions or, as a rather indulgent specialty focusing mainly on glamour and cosmesis. This study focuses on students' perceptions of an undergraduate teaching program in plastic surgery. The reality is that highly pressured undergraduates do not have the luxury of time to consider the finer details of the specialties to which they are exposed. Their priority is to pass their examinations and, having addressed that concern, further information becomes an acceptable bonus. The conclusion is that if plastic surgeons are going to gain greater involvement in the undergraduate curriculum they must start with involvement in examinations and assessments. The students will then ensure that adequate and appropriate teaching time is allocated.

The author has surveyed students of 14 departments in Beijing Normal University Zhuhai Campus. The questionnaire which is to learn the problems faced in the recruiting, cultivation and education of undergraduate communists, mainly concentrates on 5 aspects—motivations to be a party member, requirements for a party member, activities in students’ party branches, education of communists and recruiting of party members. At last, based on the analysis of the results and according to different groups, Beijing Normal University Zhuhai Campus, as an independent college, carries on multi-level party classes, delegates the authority of party class teaching and adopts popular mode of party classes. At the same time, she combines the classes with social work, enhances the evaluating work of party members and arouses the awareness of undergraduate communists, and also promotes the training quality of undergraduate communists.

    Undergraduate nursing education includes both professional knowledge and research skills. With regard to training nursing professionals for future healthcare settings, the ability to conduct research is fundamental for nurses after they graduate from universities. However, how nursing students develop coping self-efficacy and scientific skills as a specific ability during their professional study has received little attention. We studied nursing undergraduates' scientific research ability and its associated factors in the Chinese context and evaluated their self-efficacy for coping with research tasks. A total of 134 nursing undergraduates participated in the study. A purposely designed 22-item questionnaire was used to quantify students' research ability in implementing their research projects and the associated factors. Coping self-efficacy was measured with a modified Chinese version. The mean total self-efficacy score was 50.78±6.604 (M±SD). The majority (63.4%) of the students' coping self-efficacy was at a moderate level. Having "the ability to write a manuscript before conducting research projects" (P=0.006) and "topics determined by instructors after discussion with group members" (P=0.005) were the two predictive factors of good coping self-efficacy in students. Nursing undergraduates' self-efficacy was high enough to cope with their scientific research projects, but the information on procedures needed for project application was not abundant, and new training programs might be needed to meet the needs of nursing undergraduates. We should make full use of the predictors of good coping self-efficacy and promote nursing undergraduates' research ability. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available A Review of: Mbabu, L.G., Bertram, A. B., & Varnum, K. (2013. Patterns of undergraduates’ use of scholarly databases in a large research university. Journal of Academic Librarianship, 39(2, 189-193. http://dx.doi.org/10.10.1016/j.acalib.2012.10.004 Abstract Objective – To investigate undergraduate students’ patterns of electronic database use to discover whether database use increases as undergraduate students progress into later stages of study with increasingly sophisticated information needs and demands. Design – User database authentication log analysis. Setting – A large research university in the Midwestern United States of America. Subjects – A total of 26,208 undergraduate students enrolled during the Fall 2009 academic semester. Methods – The researchers obtained logs of user-authenticated activity from the university’s databases. Logged data for each user included: the user’s action and details of that action (including database searches, the time of action, the user’s relationship to the university, the individual school in which the user was enrolled, and the user’s class standing. The data were analyzed to determine which proportion of undergraduate students accessed the library’s electronic databases. The study reports that the logged data accounted for 61% of all database activity, and the authors suggest the other 39% of use is likely from “non-undergraduate members of the research community within the [university’s] campus IP range” (192. Main Results – The study found that 10,897 (42% of the subject population of undergraduate students accessed the library’s electronic databases. The study also compared database access by class standing, and found that freshman undergraduates had the highest proportion of database use, with 56% of enrolled freshman accessing the library’s databases. Sophomores had the second highest proportion of students accessing the databases at 40%; juniors and seniors

    Research experiences for undergraduates (REU) have been shown to be effective in improving undergraduate students' personal/professional development, ability to synthesize knowledge, improvement in research skills, professional advancement, and career choice. Adding to the literature on REU programs, a new conceptual model situating REU within a context of participatory action research (PAR) is presented and compared with data from a PAR-based coastal climate research experience that took place in Summer 2012. The purpose of the interdisciplinary Participatory Action Research Experiences for Undergraduates (PAREU) model is to act as an additional year to traditional, lab-based REU where undergraduate science students, social science experts, and community members collaborate to develop research with the goal of enacting change. The benefits to traditional REU's are well established and include increased content knowledge, better research skills, changes in attitudes, and greater career awareness gained by students. Additional positive outcomes are expected from undergraduate researchers (UR) who participate in PAREU, including the ability to better communicate with non-scientists. With highly politicized aspects of science, such as climate change, this becomes especially important for future scientists. Further, they will be able to articulate the relevance of science research to society, which is an important skill, especially given the funding climate where agencies require broader impacts statements. Making science relevant may also benefit URs who wish to apply their science research. Finally, URs will gain social science research skills by apprenticing in a research project that includes science and social science research components, which enables them to participate in future education and outreach. The model also positively impacts community members by elevating their voices within and outside the community, particularly in areas severely underserved

    The Space Sciences Laboratory at UC Berkeley launched an NSF-funded Research Experience for Undergraduates (REU) program in the summer of 2015. The "Advancing Space Sciences through Undergraduate Research Experiences" (ASSURE) program recruited heavily from local community colleges and universities, and provided a multi-tiered mentorship program for students in the fields of space science and engineering. The program was focussed on providing a supportive environment for 2nd and 3rd year undergraduates, many of whom were first generation and underrepresented students. This model provides three levels of mentorship support for the participating interns: 1) the primary research advisor provides academic and professional support. 2) The program coordinator, who meets with the interns multiple times per week, provides personal support and helps the interns to assimilate into the highly competitive environment of the research laboratory. 3) Returning undergraduate interns provided peer support and guidance to the new cohort of students. The impacts of this program on the first generation students and the research mentors, as well as the lessons learned will be discussed.

    Klay, J. L.

    All undergraduates in physics and astronomy should have access to significant research experiences. When given the opportunity to tackle challenging open-ended problems outside the classroom, students build their problem-solving skills in ways that better prepare them for the workplace or future research in graduate school. Accelerator-based research on fundamental nuclear and particle physics can provide a myriad of opportunities for undergraduate involvement in hardware and software development as well as ;big data; analysis. The collaborative nature of large experiments exposes students to scientists of every culture and helps them begin to build their professional network even before they graduate. This paper presents an overview of my experiences - the good, the bad, and the ugly - engaging undergraduates in particle and nuclear physics research at the CERN Large Hadron Collider and the Los Alamos Neutron Science Center.

    This study evaluated the effect of a structured education programme on improving the self-reflection skills of Chinese nursing undergraduates in managing clinical situations. Johns' Structured Reflection Model was used as a framework for the development of the education programme. Thirty-eight nursing undergraduates attended a 3-hour interactive workshop on reflective skills and were encouraged to practise the skills learned under the guidance of a nurse instructor during their 4-week clinical practicum. The findings indicated that the programme was helpful in improving the undergraduates' reflective skills though only a few of them reached the highest level as critical reflectors. Some undergraduates identified time constraints and the lack of a trusting relationship with their nurse instructor as barriers to their reflective learning. The findings may help nurse educators develop education programmes with structured learning strategies to promote nursing undergraduates' self-refection in clinical practice.

    Health disparities are preventable differences in the incidence, prevalence and burden of disease among communities targeted by gender, geographic location, ethnicity and/or socio-economic status. While biomedical research has identified partial origin(s) of divergent burden and impact of disease, the innovation needed to eradicate health disparities in the United States requires unique engagement from biomedical engineers. Increasing awareness of the prevalence and consequences of health disparities is particularly attractive to today's undergraduates, who have undauntedly challenged paradigms believed to foster inequality. Here, the Department of Biomedical Engineering at The City College of New York (CCNY) has leveraged its historical mission of access-and-excellence to integrate the study of health disparities into undergraduate BME curricula. This article describes our novel approach in a multiyear study that: (i) Integrated health disparities modules at all levels of the required undergraduate BME curriculum; (ii) Developed opportunities to include impacts of health disparities into undergraduate BME research projects and mentored High School summer STEM training; and (iii) Established health disparities-based challenges as BME capstone design and/or independent entrepreneurship projects. Results illustrate the rising awareness of health disparities among the youngest BMEs-to-be, as well as abundant undergraduate desire to integrate health disparities within BME education and training.

    To assess the frequency of Depression, Anxiety and Stress (DAS) among the undergraduate physiotherapy students. A descriptive cross sectional study was conducted in various Physiotherapy Institutes in Sindh, Pakistan among undergraduate physiotherapy students. The total duration of this study was 4 months from September, 2016 to January, 2017. Data was collected from 267 students with no physical and mental illness; more than half were female students 75.3%. They were selected through Non probability purposive sampling technique. A self-administered standardized DASS (depression, anxiety and stress scale) was used to collect data and result was analyzed using its severity rating index. Data was entered and analyzed by using SPSS version 21. Descriptive statistics including the frequency of depression, anxiety, stress and demographic characteristic of the participant was collected. The mean age of students was 19.3371±1.18839 years. The Frequency of depression, anxiety and stress found among undergraduates Physiotherapy students was 48.0%, 68.54% and 53.2%, respectively. It was observed that the frequency of depression, anxiety and stress among physiotherapy undergraduates students were high. It suggests the urgent need of carrying out evidence based Psychological health promotion for undergraduate Physiotherapy students to control this growing problem.

    Producing undergraduates capable of broad, independent thinking is one of the grand challenges in science education. Experience-based learning, specifically hands-on research, is one mechanism for increasing students' ability to think critically. With this in mind, we created a two-semester long research program called SUPER (Skills for Undergraduate Participation in Ecological Research) aimed at teaching students to think like scientists and enhancing the student research experience through instruction and active-learning about the scientific method. Our aim was for students to gain knowledge, skills, and experience, and to conduct their own research. In the first semester, we hosted active-learning workshops on "Forming Hypotheses", "Experimental Design", "Collecting and Managing Data", "Analysis of Data", "Communicating to a Scientific Audience", "Reading Literature Effectively", and "Ethical Approaches". Each lesson was taught by different scientists from one of many ecological disciplines so that students were exposed to the variation in approach that scientists have. In the second semester, students paired with a scientific mentor and began doing research. To ensure the continued growth of the undergraduate researcher, we continued the active-learning workshops and the students attended meetings with their mentors. Thus, the students gained technical and cognitive skills in parallel, enabling them to understand both "the how" and "the why" of what they were doing in their research. The program culminated with a research poster session presented by the students. The interest in the program has grown beyond our expectations, and we have now run the program successfully for two years. Many of the students have gone on to campus research jobs, internships and graduate school, and have attributed part of their success in obtaining their positions to their experience with the SUPER program. Although common in other sciences, undergraduate research experiences are

    The classroom is the main venue for undergraduate teaching. It is worth pondering how to cultivate undergraduate's research ability in classroom teaching. Here we introduce the practices and experiences in teaching reform in genetics for training the research quality of undergraduate students from six aspects: (1) constructing the framework for curriculum framework systematicaly, (2) using the teaching content to reflect research progress, (3) explaining knowledge points with research activities, (4) explaining the scientific principles and experiments with PPT animation, (5) improving English reading ability through bilingual teaching, and (6) testing students' analysing ability through examination. These reforms stimulate undergraduate students' enthusiasm for learning, cultivate their ability to find, analyze and solve scientific problems, and improve their English reading and literature reviewing capacity, which lay a foundation for them to enter the field of scientific research.

    Full Text Available The goal of an undergraduate laboratory course should be not only to introduce the students to biology methodologies and techniques, but also to teach them independent analytical thinking skills and proper experiment design.  This is especially true for advanced biology laboratory courses that undergraduate students typically take as a junior or senior in college.  Many courses achieve the goal of teaching techniques, but fail to approach the larger goal of teaching critical thinking, experimental design, and student independence.  Here we describe a study examining the application of the scaffolding instructional philosophy in which students are taught molecular techniques with decreasing guidance to force the development of analytical thinking skills and prepare undergraduate students for independent laboratory research. This method was applied to our advanced molecular biology laboratory class and resulted in an increase of confidence among the undergraduate students in their abilities to perform independent research.

    This exploratory case study examined an interprofessional placement of undergraduate students from nutrition, nursing, early childhood education, and child and youth care who collaborated to develop and deliver four healthy-living modules to secondary school students in Canada. An inductive thematic analysis was used to describe the teamwork that occurred between students. Data collected included focus groups with undergraduate students and preceptors, undergraduate students' reflections and secondary school students' evaluations of the modules delivered. Two major themes that emerged from all data sources were "team functioning" and "shift in perspectives". The undergraduate students identified several ways that facilitated their successful and positive teamwork with one another and also expressed how the placement experience improved their interprofessional skills. Findings from this study are discussed in relation to contact theory (Allport, 1954) and self-presentation theory (Goffman, 1963). This study suggests that providing undergraduate students with interprofessional placements in an educational setting can enhance interprofessional teamwork opportunities for students of various disciplines.

    Full Text Available Programming courses become prominent as one of the courses in which undergraduate students are unsuccessful especially in departments which offer computer education. Students often state that these courses are quite difficult compared to other courses. Therefore, a qualitative phenomenological approach was used to reveal the reasons of the failures of the undergraduate students in programming courses and to examine the difficulties they confronted with programming. In this scope, the laboratory practices of the Internet Programming course were observed in fall term of the 2013-2014 academic year in a university at central Anatolia. Interviews were made with 12 undergraduate students taking this course. Finally, the difficulties students experienced in the programming were determined as programming knowledge, programming skills, understanding semantics of the program, and debugging. Students emphasized that the biggest causes of failure in programming languages are lack of practice, not using algorithms and lack of knowledge. In addition, it was seen that the students who had high programming experience possess higher programming success and self-efficacy related to programming

    Directory of Open Access Journals (Sweden)

    Dominic Harvey

    2016-07-01

    Full Text Available AbstractThe Bologna Process model of higher education has been introduced into some Australian universities since 2008. This model promoted university study through a liberal arts philosophy that advanced a worldview approach at the undergraduate level. The model generalised the student experience and eliminated undergraduate specialisation. An interesting situation for music undergraduate study thus arose. Expertise and expert performance research has argued an opposing educational approach, namely: Extensive long-term commitment through focused practical engagement and specialised tuition as prerequisites to achieving musical mastery, especially in performance. Motivation research has shown that the majority of this specialised development in pre-university years would be accessed and reinforced predominantly through private music tuition. Drawing on this contextual literature, commencing university music undergraduates would have expectations of their prospective study founded from two historical influences. The first: How undergraduates had accessed pre-university music tuition. The second: How and in what ways undergraduates’ pre-university musical activities were experienced and reinforced. Using usefulness and importance measures, the study observed the expectations of students about to commence music undergraduate studies at three representative Australian university music schools. One of these universities operated the Bologna styled model. No other known Australian study has investigated this implementation for any effects upon music undergraduate expectations. How much commencing music undergraduates would draw on their pre-university music instruction and experiences to predict their usefulness and importance expectations formed the basis for this investigation. Strong relationships between usefulness and importance were found across all units of study. Despite strong correlations across all units of study between usefulness and

    2012-07-01

    An example of entropy enigma with a controlled CFT dual was recently studied in [1]. The enigmatic bulk configurations, considered within the STU model, can be mapped under spectral flow into black rings with three monopole and dipole charges. Even though the bulk and CFT configurations existed in the same region of parameter space, the Bekenstein-Hawking entropy of the bulk configurations was found to be lower than the microscopic entropy from the CFT. While it is possible that the difference in entropy is due to the bulk and boundary configurations being at different points in the moduli space, it is also possible that the bulk configurations embeddable within the STU model are not the most entropic. New families of BPS black ring solutions with four electric and four dipole magnetic charges have recently been explicitly constructed in [2]. These black rings are not embeddable within the STU model. In this paper we investigate if these black rings can be entropically dominant over the STU model black rings. We find that the new black rings are always entropically subdominant to the STU-model black rings. However, for small fourth dipole charge these black rings continue to be dominant over the BMPV in a small region of parameters and are thus enigmatic.

    Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical “big data” opens the possibility of utilizing biocuration as a means to mine today’s data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8–50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week. PMID:26557796

    An Undergraduate Nurse Employment Demonstration Project (UNDP) was implemented in four Health Service Areas in British Columbia with a concurrent evaluation study. This demonstration project comprised the development and implementation of a new position in the BC healthcare system. The position enabled third- and fourth-year nursing students to be employed at their level of education. The purposes of the evaluation were to explore the feasibility and outcomes of this type of paid undergraduate student nurse employment. The three-year project and evaluation included both implementation and outcome analysis. The implementation evaluation design was descriptive and prospective, involving multiple data sources. The outcome evaluation design was quasi-experimental, with intervention and comparison groups. Learning outcomes for undergraduate nurses were increased confidence, organizational ability, competency and ability to work with a team. Workplace outcomes were increased unit morale, help with workload and improved patient care. New graduates with undergraduate nurse experience reported less time required for orientation and transition than other graduates who did not have this experience, and workplace nurses viewed these new graduates as more job-ready than other new graduates. After 21 months, new graduates with undergraduate nurse experience were less likely to move to other employment than other new graduates. Results from the four Health Service Areas indicated that the paid undergraduate nurse position was feasible and that outcomes benefited students, new graduates and workplaces. The undergraduate nurse position is now being implemented throughout all Health Service Areas in British Columbia.By 2000, concerns in British Columbia about the nursing workforce, workplace and patient safety had escalated to the point where diverse stakeholder groups were prepared to work together in new ways to prepare nursing graduates to be more job-ready, to recruit and retain

    Blended learning is a combination of online and face-to-face learning and is increasingly of interest for use in undergraduate medical education. It has been used to teach clinical post-graduate students pharmacology but needs evaluation for its use in teaching pharmacology to undergraduate medical students, which represent a different group of students with different learning needs. An existing BSc-level module on neuropharmacology was redesigned using the Blended Learning Design Tool (BLEnDT), a tool which uses learning domains (psychomotor, cognitive and affective) to classify learning outcomes into those taught best by self-directed learning (online) or by collaborative learning (face-to-face). Two online courses were developed, one on Neurotransmitters and the other on Neurodegenerative Conditions. These were supported with face-to-face tutorials. Undergraduate students' engagement with blended learning was explored by the means of three focus groups, the data from which were analysed thematically. Five major themes emerged from the data 1) Purpose and Acceptability 2) Structure, Focus and Consolidation 3) Preparation and workload 4) Engagement with e-learning component 5) Future Medical Education. Blended learning was acceptable and of interest to undergraduate students learning this subject. They expressed a desire for more blended learning in their courses, but only if it was highly structured, of high quality and supported by tutorials. Students identified that the 'blend' was beneficial rather than purely online learning.

    Full Text Available Depressive disorders are the most typical disease affecting many different factors of humanity. University students may be at increased risk of depression owing to the pressure and stress they encounter. Therefore, the purpose of this study is comparing the level of depression among male and female athletes and non-athletes undergraduate student of private university in Esfahan, Iran. The participants in this research are composed of 400 male and female athletes as well as no-athletes Iranian undergraduate students. The Beck depression test (BDI was employed to measure the degree of depression. T-test was used to evaluate the distinction between athletes and non-athletes at P≤0.05. The ANOVA was conducted to examine whether there was a relationship between level of depression among non-athletes and athletes. The result showed that the prevalence rate of depression among non-athlete male undergraduate students is significantly higher than that of athlete male students. The results also presented that level of depression among female students is much more frequent compared to males. This can be due to the fatigue and lack of energy that are more frequent among female in comparison to the male students. Physical activity was negatively related to the level of depression by severity among male and female undergraduate students. However, there is no distinct relationship between physical activity and level of depression according to the age of athlete and nonathlete male and female undergraduate students. This study has essential implications for clinical psychology due to the relationship between physical activity and prevalence of depression.

    Chuenjitwongsa, S; Oliver, R G; Bullock, A D

    2018-02-01

    The aim of undergraduate dental education is to provide competent dentists to serve societal needs and improve population oral healthcare. Competency-based education has influenced the development of dental education for decades but this term is problematic. This article explores components of competency-based undergraduate health professional education in order to help the dental profession have a better understanding of the context and purposes of undergraduate dental education. This is a discussion paper based on a wide reading of the literature on the education of health professionals with a specific focus on competency-based undergraduate education. Competence comprises an integration of knowledge, skills and attitudes indicating a capability to perform professional tasks safely and ethically. The process of becoming a competent practitioner is complex. Four characteristics of competency-based education are: curriculum components and content shaped by societal needs; focused on student-centred learning; learning achievement; and limited attention to time-based training and numerical targets. Alongside a competency-based approach, undergraduate dental education can be influenced by institutional features and external factors but these receive little consideration in the literature. Understanding competence, competency-based education, and institutional and external factors will help to improve educational quality, define roles and professional development for the dental educator, and inform further research. © 2016 John Wiley & Sons A/S.

    Severson, S.

    2010-12-01

    I present a model for designing student research internships that is informed by the best practices of the Center for Adaptive Optics (CfAO) Professional Development Program. The dual strands of the CfAO education program include: the preparation of early-career scientists and engineers in effective teaching; and changing the learning experiences of students (e.g., undergraduate interns) through inquiry-based "teaching laboratories." This paper will focus on the carry-over of these ideas into the design of laboratory research internships such as the CfAO Mainland internship program as well as NSF REU (Research Experiences for Undergraduates) and senior-thesis or "capstone" research programs. Key ideas in maximizing student learning outcomes and generating productive research during internships include: defining explicit content, scientific process, and attitudinal goals for the project; assessment of student prior knowledge and experience, then following up with formative assessment throughout the project; setting reasonable goals with timetables and addressing motivation; and giving students ownership of the research by implementing aspects of the inquiry process within the internship.

    2017-11-01

    Numerical computation has many pedagogical advantages: it develops analytical skills and problem-solving skills, helps to learn through visualization, and enhances physics education. Unfortunately, numerical computation is not taught to undergraduate education physics students in Indonesia. Incorporate numerical computation into the undergraduate education physics curriculum presents many challenges. The main challenges are the dense curriculum that makes difficult to put new numerical computation course and most students have no programming experience. In this research, we used case study to review how to integrate numerical computation into undergraduate education physics curriculum. The participants of this research were 54 students of the fourth semester of physics education department. As a result, we concluded that numerical computation could be integrated into undergraduate education physics curriculum using spreadsheet excel combined with another course. The results of this research become complements of the study on how to integrate numerical computation in learning physics using spreadsheet excel.

    Full Text Available Descreve-se a ocorrência e analisa-se as causas de anomalias dentárias em Artibeus lituratus (Olfers, 1818 e A. fimbriatus Gray, 1838 (Chiroptera: Phyllostomidae provenientes de populações do Estado do Rio Grande do Sul, sul do Brasil. São discutidas, com base no material examinado e em ampla revisão da literatura, as variações quanto à presença dos terceiros molares superior e inferior entre diferentes espécies de Artibeus Leach, 1821. Foram analisados 104 crânios de A. lituratus e 44 de A. fimbriatus quanto à fórmula dentária. Em A. lituratus ocorreram dois casos de dentes extranumerários, um incisivo superior e um terceiro molar superior direito, e um de agênese dentária dos terceiros molares inferiores. Em A. fimbriatus constatou-se a ocorrência de um segundo pré-molar superior direito extranumerário. As ocorrências do terceiro molar superior em A. lituratus e do segundo pré-molar superior em A. fimbriatus são casos de atavismos. Em Artibeus (Artibeus ocorrem variações quanto à presença do terceiro molar superior, de maior ou menor intensidade, em praticamente todas as espécies. Estas variações ocorrem tanto a nível intrapopulacional quanto geográfico. Já o terceiro molar inferior está ausente em baixa freqüência em várias populações de diferentes espécies. Os terceiros molares superiores e inferiores estão em processo de desaparecimento na linhagem dos Artibeus (Artibeus. O fato destes dentes já não ocorrerem em algumas espécies, terem ocorrência variável em outras e serem sempre estruturas reduzidas e simplificadas, sem função na mastigação, são indicativos deste processo evolutivo. A variação intensa observada quanto à ocorrência do terceiro molar superior inviabiliza o seu uso como caráter útil na identificação de espécies.This paper describes and analyzes the causes of dental formula anomalies in the bats Artibeus lituratus (Olfers, 1818 and Artibeus fimbriatus Gray, 1838

    2004-05-01

    Full Text Available Na literatura pertinente à relação entre reabsorções dentárias em Ortodontia e hereditariedade destacam-se quatro artigos: Newman21, Harris, Kineret, Tolley16, Al-Qawasmi et al.¹ e de Al-Qawasmi et al². O trabalho de Newman21 possui o mérito do pioneirismo, mas apesar disto não conseguiu provar ou mostrar fortes evidências da relação entre reabsorções dentárias e hereditariedade. As falhas metodológicas e o pequeno número de gerações e famílias pesquisadas não permitiram afirmações conclusivas, como reconhece explicitamente o próprio autor. A principal falha está na amostra, constituída por raízes curtas sem preocupar-se com a causa das mesmas, incluindo-se raízes curtas próprias do desenvolvimento dentário. Também não houve critério definido para diagnosticar o que é uma raiz curta, foi um critério muito subjetivo. No final nota-se um pequeno número de famílias e gerações, pois foram analisados pais e filhos em apenas 17 heredogramas. Durante o trabalho não houve preocupação com a padronização do tipo de discrepâncias faciais e dentárias, do tipo de má oclusão, da morfologia radicular ou da crista óssea, do tipo de diagnóstico e plano de tratamento, nem tampouco da técnica e dos operadores dos tratamentos ortodônticos. No final considerou-se como causa de maior reabsorção de dentes com raízes curtas, após o tratamento ortodôntico, um potencial de reabsorção ao qual atribui-se um caráter genético, mas sem qualquer fundamentação nos resultados. Hoje, sabe-se que as raízes curtas quando movimentadas apresentam maior índice de reabsorção, pois concentram mais forças no ligamento periodontal, com maior possibilidade lesão na camada cementoblástica e conseqüente reabsorção radicular8, 9, 14,15, 23.Four articles stand out when analyzing literature concerning root resorption in Orthodontics and heritability: Newman21, Harris, Kineret, Tolley16 and Al-Qawasmi et al.¹ e Al

  12. A Tiered Mentoring Model of Exposing and Engaging Students with Research Throughout the Undergraduate Curriculum

    Guerard, J.; Hayes, S. M.

    2015-12-01

    Incorporating research into undergraduate curricula has been linked to improved critical thinking, intellectual independence, and student retention, resulting in a graduating population more ready for the workforce or graduate school. We have designed a three-tier model of undergraduate chemistry courses that enable first-year students with no previous research experience to gain the skills needed to develop, fund and execute independent research projects by the close of their undergraduate studies. First-year students are provided with context through a broadly focused introductory class that exposes them to current faculty research activities, and also gives them direct experience with the research process through peer mentored research teams as they participate in faculty-directed projects. Mid-career undergraduate students receive exposure and support in two formats: illustrative examples from current faculty research are incorporated into lessons in core classes, and courses specially designed to foster research independence. This is done by providing content and process mentoring as students develop independent projects, write proposals, and build relationships with faculty and graduate students in research groups. Advanced undergraduates further develop their research independence performing student-designed projects with faculty collaboration that frequently result in tangible research products. Further, graduate students gain experience in mentoring though formal training, as well as through actively mentoring mid-career undergraduates. This novel, integrated approach enables faculty to directly incorporate their research into all levels of the undergraduate curriculum while fostering undergraduates in developing and executing independent projects and empowering mentoring relationships.

    Nazir, Tahir; Wallis, Simon; Higham, Jackie; Newton, Kate; Pugh, Mark; Woywodt, Alexander

    2014-11-01

    Medical Admission Units (MAUs) were introduced in the UK in the 1980s primarily driven by a governance and service improvement agenda. In the UK this has led to the development of Acute Medicine as a specialty in its own right, together with a strong role of this specialty in postgraduate teaching. In contrast, the role of MAUs, if any, in undergraduate medical education is currently unclear. Prompted by an expansion of our undergraduate student numbers, our aim was to establish a Year 3 undergraduate firm on a 33-bedded MAU in a large academic teaching hospital in the National Health Service (NHS). Despite initial scepticism from clinicians, managers, and educators, the new firm placement on MAU became an instant success and continues to attract excellent feedback from our Year 3 undergraduate students. Students enjoy the bedside teaching with a high percentage of consultant-delivered teaching and also liked the involvement of Foundation Doctors. Here, we report our experience on how to make such a firm work, based on student feedback and the tutors' experience. We provide an overview and a step-by-step guide of how to construct a successful new undergraduate firm on a busy MAU. We also discuss opportunities and challenges and discuss the relevant literature. We conclude that undergraduate teaching is feasible and rewarding in an extremely busy MAU setting. We note that identifying enthusiastic educators within the MAU team, utilisation of peripheral learning opportunities, structured timetables and induction, and a robust framework for quality assurance are all crucial to success.

    In 2004 the Hatfield Marine Science Center (HMSC) at Oregon State University (OSU) established a Research Experience for Undergraduates (REU) program to engage undergraduate students in hands-on research training in the marine sciences. The program offers students the opportunity to conduct research focused on biological and ecological topics, chemical and physical oceanography, marine geology, and atmospheric science. In partnership with state and federal government agencies, this ten-week summer program has grown to include 20+ students annually. Participants obtain a background in the academic discipline, professional development training, and research experience to make informed decisions about careers and advanced degrees in marine and earth system sciences. Professional development components of the program are designed to support students in their research experience, explore career goals and develop skills necessary to becoming a successful young marine scientist. These components generally include seminars, discussions, workshops, lab tours, and standards of conduct. These componentscontribute to achieving the following professional development objectives for the overall success of new emerging undergraduate researchers: Forming a fellowship of undergraduate students pursuing marine research Stimulating student interest and understanding of marine research science Learning about research opportunities at Oregon State University "Cross-Training" - broadening the hands-on research experience Exploring and learning about marine science careers and pathways Developing science communication and presentation skills Cultivating a sense of belonging in the sciences Exposure to federal and state agencies in marine and estuarine science Academic and career planning Retention of talented students in the marine science Standards of conduct in science Details of this program's components, objectives and best practices will be discussed.
